[Announce] 2.6.29-rc4-rt1
Thomas Gleixner
announce a refactored preempt-rt patch against linux-2.6.29-rc4.
The patch is working on x86 (32 and 64bit) but we have not yet updated
ARM, PPC and MIPS (work in progress).
We also dropped some experimental features of the base preempt-rt
queue 2.6.26.8-rt15 simply because we wanted to survive the forward
port over 3 kernel releases with the least amount of surprises. These
features (e.g. multiple reader PI locks) are not essential for the
preempt-rt functionality and need some serious overhaul anyway.
The interested -rt observer might have noticed that we based our work
on the 2.6.26.8-rt15 patch queue and did not pick the git-rt tree
which is based on 2.6.28. The reason for this is that we wanted to pick
the most stable patch queue and the git-rt tree has a lot of rewritten
new code. Our work is not making the work which was done over the last
months in the git-rt tree obsolete, quite the contrary: we want to
provide a stable yet latest-kernel based foundation and integrate those
changes gradually, as they become ready.
The further plan for the new -rt series is to merge it fully into git
and integrate it into the -tip git tree so it gets the same treatment
as all of our -tip based work: fully automated compile and boot
testing. Furthermore an automated multi architecture -rt performance
regression test based on the same infrastructure is currently being
built.
The integration into the -tip tree also allows us to seperate out parts
of -rt which are ready for mainline more easily and integrate them
with our usual propagation to mainline.
The structure of the patches is likely to change over the next days
when we tackle the git integration, but we appreciate your feedback in
the form of comments, bugreports and patches.
Enough said. You can find the new patches at the following location:
http://www.kernel.org/pub/linux/kernel/projects/rt/
Information on the RT patch can be found at:
http://rt.wiki.kernel.org/index.php/Main_Page
to build the 2.6.29-rc4-rt1 tree, the following patches should be
applied:
http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.29-rc4.tar.bz2
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc4-rt1.bz2
The broken out patches are also available at the same download
location.
Enjoy !
Thomas, Ingo

Note, it's a wicked bug: I can't reproduce it anymore.
I would have been glad to give you an irqsoff trace but I can't :-)
Oh yes I have two other warnings, for the second one, I'm not sure
this is really only present in -rt.
The first one, a lockdep warning:

hm, that's a complex one - we do kfree() from IPI context, dunno why this
never triggered in our testing of -rt1.

The patch below might do the trick - it offloads this to a softirq.

Subject: rt: fix ipi kfree(), introduce IPI_SOFTIRQ
From: Ingo Molnar <mi...@elte.hu>
Date: Thu Feb 12 09:06:11 CET 2009
in 2.6.28 generic_smp_call_function_interrupt() grew a kfree(),
which is a rather complex, sleepable method under -rt. But the
IPI code runs as a hardirq - which cannot run such code.
So defer this work to a softirq context instead. It still stays
on the same CPU so the percpu IPI assumptions are upheld.

On a second thought ...
I think we could eliminate the kfree() instead, and keep the
atomicity of IPI cross-calls. Linus expressed doubts about
the IPI kmalloc()/kfree() pair we do in the generic SMP IPI
code, suggesting that it probably does not help performance
all that much - so such a change might be upstream-able as well
and would keep -rt closer to mainline.

ok, it's lightly tested now: it built and booted up fine to X with your config.

Which comes from:
if (WARN_ON_ONCE(in_irq()))
return -EDEADLK;
This warning is surprising, as it clearly comes from a softirq
context.
The in_irq() definition looks like this on -rt:
#define in_irq() (hardirq_count() || (current->flags & PF_HARDIRQ))
hardirq_count() is correct, but looking at PF_HARDIRQ's definition in sched.h:
#define PF_EXITPIDONE 0x00000008 /* pi exit done on shut down */
#define PF_VCPU 0x00000010 /* I'm a virtual CPU */
#define PF_HARDIRQ 0x08000020 /* hardirq context */
#define PF_NOSCHED 0x00000020 /* Userspace does not expect scheduling */
#define PF_FORKNOEXEC 0x00000040 /* forked but didn't exec */
Reveals that due to a typo it not only overlaps the PF_NOSCHED bit, but
also has a spurious 0x08000000 component.
Move it to a free slot: 0x00000080.

The reason is that when we forward ported the definition, i first moved it
to the 0x08000000 slot - but that slot was already taken. (our PF_ task
flag space is really crowded ...)
Then i moved it to a free spot, 0x20. Or so i thought: a later -rt patch
in the queue introduced PF_NOSCHED which overlapped it.
But the bigger problem was the spurious 0x08000000 component, which overlaps
with:
#define PF_SOFTIRQ 0x08000000 /* softirq context */
Explaining why the warning triggered in ksoftirqd ;-)
Anyway, my fix should solve this. Do you still see the lockup under X? (make
sure you also have the IPI fix applied, see the patch in this same thread.)

ok, i made it unconditional (not just a PREEMPT_RT hac) and did the
cleanup below on top of it.
I dont think repeat, queued IPIs are all that interesting from a
performance point of view. If they are, it will all be clearly
bisectable.

Right, except I really don't like the smp_call_function_many() slow path
that's now the only path.
Rusty did that I think, but he also had some idea on how to fix it, I
think it boiled down to sticking a count in the call data instead of the
full cpumask.
So I'd rather we first fix that code, and then remove the kmalloc
all-together like you propose here.

i tried your config and after a few bootups the warning did trigger.
It's the new resource counter code. The IRQ flags disabling it does
seems a bit dubious to me. Peter, what do you think?

The reason is the raw IRQ flag use of kernel/res_counter.c.
The irq flags tricks there seem a bit pointless: it cannot
protect the c->parent linkage because local_irq_save() is
only per CPU.
So replace it with _nort(). This code needs a second look.

I'm sorry for no knowledge about RT. Could you teach me what
local_irq_save_nort() does ?
Hmm, how about just replacaing _irq() with preempt_disable()/enable() ?
xxx_nort() is better ?
AFAIK, these will not be called from irq context. (Added Balbir to CC:)

_nort() will just turn them into NOPs in essence.
The question is, are these local IRQ flags manipulations really needed
in this code, and if yes, why?

Right, I can't see a way around carrying that cpumask, there's just too
much that can go wrong without it.
So it put in unconditionally, how about this?

Subject: generic-smp: remove single ipi fallback for smp_call_function_many()
In preparation of removing the kmalloc() calls from the generic-ipi code
get rid of the single ipi fallback for smp_call_function_many().
Because we cannot get around carrying the cpumask in the data -- imagine
2 such calls with different but overlapping masks -- put in a full mask.

Hmm, I think this bit ought to go in rcu_free_call_data(), otherwise we
can have that same race again..
I'd better put a comment in on why we use RCU here.

Ok, I tested it through 3 bootups and it did not triggered.
But it's absolutely not a guarantee, as I said, I tried to reproduce it
with several bootups yesterday and I couln't see it again.
But by reading the warning and your patch, yes it is supposed to solve it :)
BTW, a small thing:

The reason for which I wanted to send an irqsoff trace is that the above lines are false.
addr2line -e vmlinux ffffffff8025449d
/home/me/linux/rt/linux-2.6.29-rc4/kernel/fork.c:1107 (before your patch)
Which is this area in copy_process:
#ifdef CONFIG_NUMA
p->mempolicy = mpol_dup(p->mempolicy);
if (IS_ERR(p->mempolicy)) {
retval = PTR_ERR(p->mempolicy);
p->mempolicy = NULL;
goto bad_fork_cleanup_cgroup;
}
mpol_fix_fork_child_flag(p); // <-- 1107
#endif
Nothing here disables irq.
That's why I wanted to provide an irqsoff trace. But, heh I only had to read
res_counter_charge() :-)
Anyway, there is a problem with these hardirqs/softirqs last disabled...

copy_process() has:
#endif
p->hardirq_enable_ip = 0;
p->hardirq_enable_event = 0;
p->hardirq_disable_ip = _THIS_IP_;
p->hardirq_disable_event = 0;
p->softirqs_enabled = 1;
p->softirq_enable_ip = _THIS_IP_;
p->softirq_enable_event = 0;
p->softirq_disable_ip = 0;
p->softirq_disable_event = 0;
p->hardirq_context = 0;
p->softirq_context = 0;
#endif
the sequence count of 0 basically tells you it hasn't been set yet.

It'll work, but its not mergable upstream like this, it greatly
pessimizes the smp_function_call() performance.

maybe we should initialize it to -1 to make this more apparent?

Oh I see now, thanks Peter.

Or why not set p->{hard,soft}irq_disable_ip = NULL ? (or 0, I don't know its type).

I think the current state makes sense, it reflects the actual state of
copy_process.

It is to reflect the actual state at copy_process(), although I think
here's a little buglet:
ifdef CONFIG_TRACE_IRQFLAGS
p->irq_events = 0;
#ifdef __ARCH_WANT_INTERRUPTS_ON_CTXSW
p->hardirqs_enabled = 1;
#else
p->hardirqs_enabled = 0;
#endif
p->hardirq_enable_ip = 0;
p->hardirq_enable_event = 0;
p->hardirq_disable_ip = _THIS_IP_;
p->hardirq_disable_event = 0;
p->softirqs_enabled = 1;
p->softirq_enable_ip = _THIS_IP_;
p->softirq_enable_event = 0;
p->softirq_disable_ip = 0;
p->softirq_disable_event = 0;
p->hardirq_context = 0;
p->softirq_context = 0;
#endif
I think the hardirq_enable/disable_ip should also depend on
__ARCH_WANT_INTERRUPTS_ON_CTXSW.

Wont the first CPU that runs the callback unlock this? And then we run the
risk of two back to back callers on the same CPU, having the second

No, there's a ref count in there that ensures the last one unlocks it.
But that's still not enough, the global queue is RCU protected.
Suppose you have 4 cpus, and use smp_function_call_mask() to 2 others,
now its possible the 4th is also doing global ipis and is traversing the
global queue.
Therefore, if you remove the cfd when its done, it might be the 4th cpu
is in it trying to iterate to the next entry --> BANG.
The solution used is RCU freeing cfd's. This also means we have to RCU
free the LOCK flag, sadly an RCU grace period is waaaay too long to spin
wait on.
Hence this whole solution is not quite feasible.
There's various alternative solutions, but I'm not quite sure which
makes most sense.
The one I'm currently pondering is using the global queue only for
all-but-self cfd's, this matches the all-but-self ipi APIC case.
For smaller masks we could queue a csd per queue and send single ipis.

We needed the local IRQ flags, since these counters are updated from
page fault context and from reclaim context with lru_lock held with
IRQ's disabled. I've been thinking about replacing the spin lock with
seq lock, but have not gotten to it yet.

Ah, in that case we can get away with _nort I think, as both those
contexts are preemptable on -rt.

Hmm ? I can't understand. Why we have to disable IRQ here again ?
And,
- try_to_unmap() is called in shrink_page_list(), there, no zone->lru_lock.
- page fault path doesn't hold zone->lru_lock.
My concern is only shmem. But I think it doesn't call charge() within lock, actually.
Thanks,

Clarification :)
res_counter_charge() is called from
- page fault
=> under down_read(mmap_sem), lock_page() may be held. IRQ=ENABLED)
- add_to_page_cache
=> under lock_page(), mapping->tree_lock is *not* held, IRQ=DISABLED
- shmem
=> info->lock is held, we use __GFP_NOWAIT here. IRQ=ENABLED
- shmem
=> info->lock is *not* held with GFP_KERNEL here, IRQ=ENABLED.
- migration
=> under lock_page() and mmap_sem, IRQ=ENABLED
res_counter_uncharge() is called from
- page_remove_rmap()//(Only when ANON)
=> anon_vma->lock and pte_lock(),lock_page() can be held. IRQ=ENABLED?
- remove_from_page_cache()
=> lock_page() and mapping->tree_lock is held, IRQ=DISABLED.
Summary:
"Charge" is considered as heavy operation and the call path is placed where the
thread can sleep, AMAP.
"Uncharge" is considered as light operation and call path is under some # of
spinlocks.

Hi,
It fixes the rt-concerned warning I had.
Now, a new little lockdep info, tell me if you need my config, I changed

Oh and I just tested the tracers.
It seems to run fine for all of them except sysprof.
It passes the self-test but doesn't produce any trace when I manually try.
Not completely sure this is only in -rt so I'm pulling very latest -tip
and will see if I find the same problem there.
Frederic Weisbecker
About sysprof, it's an -rt problem, I don't see it on -tip.
The sysprof hrtimer callback is never called.
I'm digging to see what is happening.
Frederic Weisbecker
I didn't put my ftrace_printk at the right place.
It doesn't come from hrtimer.
The problem comes from get_irq_regs() which always returns NULL on the
sysprof hrtimer calback, then the trace is immediately dropped
by sysprof.
That's weird, smp_apic_timer_interrupt() calls set_irq_regs() so
it should find it.
Now I'm preempted by my bed.

Ah, that makes sense - under -rt the default hrtimer execution is to
execute in a softirq context. Could you try the patch below please,
does it fix sysprof?

------------------>
Subject: rt: sysprof hrtimer fix
From: Ingo Molnar <mi...@elte.hu>
Date: Fri Feb 13 08:22:14 CET 2009
Frederic Weisbecker noticed that sysprof does not work under
29-rt2, and tracked it down to a NULL result that get_irq_regs()
gives to the sysprof plugin.
The reason for the NULL is that it executes in the HRTIMER_SOFTIRQ
context, hence it does not interrupt any real context and thus
there's no IRQ registers to take a look at.
Since the sysprof functionality is atomic, the fix is to move the
sysprof hrtimers to hardirq context.

Yes! Thanks :-)

So, just a thing.
-rt make the hrtimer's timers running on softirq context because the hrtimer_interrupt
doesn't run as a threaded interrupt, and then it is not preemptible right?
In that case, sysprof will continue to run in hardirq context, as before, and
it will considerably increase the latency. And that matters here.
So I think it is important to put it on the reminder:
-------------------->
Subject: [PATCH] rt: add sysprof to the latency overhead reminder
From: Frederic Weisbecker <fwei...@gmail.com>
Since sysprof uses the hrtimer on hardirq with interrupts disabled, it
adds a latency overhead.
Add it to the latency reminder.

Not at all.
But when I find some time, I will compare some rt average tests with and without sysprof.

OK, if you really want this, please just change it to:
unsigned long cpumask_bits[BITS_TO_LONGS(CONFIG_NR_CPUS)];
The 'struct cpumask' will be undefined soon when CONFIG_CPUMASK_OFFSTACK=y,
which will prevent assignment and declaration on stack.
I'd be fascinated to see perf numbers once you kill the kmalloc. Because
this patch will add num_possible_cpus * NR_CPUS/8 bytes to the kernel which
is something we're trying to avoid unless necessary.
Thanks,
Rusty.

You're free to make it a pointer and do node affine allocations from an
init section of choice and add a hotplug handler.
But I'm not quite sure how perf is affected by size overhead on
ridiculous configs.

No, I meant "can you actually measure the perf win of this patch?". If you
did so, I missed it?
But if this patch is worthwhile, the right way to do this is make it a
cpumask_var_t, and do the alloc_cpumask_var_node() in that init routine.
Thanks,
Rusty.

Over what, the always single-ipi case, or the kmalloc case?
The thing is, we're removing that kmalloc because its somewhat of a wart
on the whole thing.

Right, and installing a hotplug handler and ... *sigh*

Hi,
Setting CONFIG_PERF_COUNTERS make my build, hang really early. Likely
before ohci1394_dma=early stuff, because firescope doesn't seem to work.
With attached config the system boots up to the point
after /etc/rc.sysinit (this is a fedora 10 system) activates the swap.
Then all I see from upstart/init is "Message from illegal source". And
the system seems to stop the boot process. Strange, isn't it?
So this is what I could capture with attached config, by inserting
"/bin/bash" into /etc/rc.sysinit after swap activation:

Hmm, this appears unimplemented on -rt, shouldn't hurt much, but could
be fixed.

Caused by CONFIG_HIGHPTE=y,
as long as TLB flushes are IPIs we really need to disable IRQs for
gup_fast() and thus will either need non-preemptible kmap or disabled
high-pte or disable the gup_fast() fast-path, which would be a shame.

Hi,
Are you interested in these BUG reports?
Without CONFIG_HIGHPTE kernel boots and seems to work correct, but I'm
hitting these two BUGs:

sg_copy_buffer() seems to disable IRQs, however since on -rt everything
is a irq-thread and kmap is preemptible, we don't appear to have that
need.
CC'd everybody who ever touched the file.

These patches in RT2:
rt-fix-ipi-kfree-introduce-ipi_softirq.patch
rt-fix-ipi-kfree-introduce-ipi_softirq-cleanup.patch
Cause a hard-lock when running dhcp on my 8-way AMD box.
Reverting them eliminates the issue.

These work with 2.6.29-rc4-rt2.
Also fixes serial console stall.
I applied them before RT and had to tweak these patches:
preempt-realtime-ipi-call-lock-raw.patch
preempt-realtime-x86_64.patch
Thanks!

I got this warning, that i never saw before with a non rt-preempt

Hi,
It's an known issue on ath5k (or 80211):
http://patchwork.kernel.org/patch/1169/
So not preempt-rt related. Perhaps it has been fixed in -rc5.

My bad. Forgot to remove the localversion-tip file.
Can you try to enable the following config options:
CONFIG_DEBUG_OBJECTS
CONFIG_DEBUG_OBJECTS_FREE
CONFIG_DEBUG_OBJECTS_TIMERS
CONFIG_DEBUG_OBJECTS_ENABLE_DEFAULT

Don't bother. Just noticed that this is nf_conntrack context. Working
on that right now.

I'm running rc6-rt3 and that problem seem to be gone (uptime of 2.5
hours in my desktop, 1.33 hours on my laptop, both running FC9 with a
2.6.29 version of the Planet CCRMA rt kernel). So far so good!

If it works for you without (plain .29-rc6), then it ought to work with.

This is similar to what was happening to me with rc6-rt2, maybe another
driver with a similar problem?

plain .29-rc6 suspends and resumes just fine.
but .29-rc6-rt3 suspends just fine, but never resumes.
Is there an early_dma thing for the resume path for 1394?

series. It contains only one new patch:
- disable CONFIG_MAXCPUS for now (undebugged runtime bug)
- fix CONFIG_HIGHMEM problems
- fix netfilter problems
- make debugobjects -rt safe
- various build fixes

Information on the RT patch can be found at:

to build the 2.6.29-rc7-rt1 tree, the following patches should be
applied:

This should be
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc7-rt1.patch.bz2
As far as i understand this is again for x86. I tried some patches to get the
ARM platform working as the platform i am working on (phytec i.mx31) is not
supported by the stable 2.6.26-rt release. The attached patches are for
reference only as i think some of them are on their way via the pengutronix
git tree and others are just hacks to get this thing compile. These patches
enable rt functionality as tested with cyclictest but the kernel is not
stable, so some pieces are missing.
So my question is, what pieces are missing on the ARM platform to get it working?
Regards
Tim
The following patches are against the 2.6.29-rc4-rt2 in an attempt to get ARM working.

Doing this in arch/arm/include/asm/bitops.h is less intrusive and it
seems to me the better place. See my patch stack.

It would be easier to check your patch if it didn't contain reverts of
earlier changes.

on top of 2.6.29-rc7-rc1 I did some ARM related fixes that you can find
at
git://git.pengutronix.de/git/ukl/linux-2.6.git v2.6.29-rc7-rt1-pu
The top commit currently isn't pretty as it contains several independant
fixes. Some of them are netX specific so you probably don't need them,
but they shouldn't hurt you either.
I will update this branch as I continue working in a non-fast-forward
manner. I use TopGit to manage this branch, you might want to use it,
too, if you intend to follow my work.
My status quo is:
Testing tracer sched_switch: PASSED
Testing tracer function: PASSED
Testing tracer irqsoff: .. no entries found ..FAILED!
Testing tracer preemptoff: .. no entries found ..FAILED!
Testing tracer preemptirqsoff: .. no entries found ..<4>------------[ cut here ]------------

FAILED!
The warning is triggered here because tracing_start is called twice in
trace_selftest_startup_preemptirqsoff's error path[1].
I researched for some time now why the tracers doesn't pass the
self-tests, but without success. It's bed time and any hints are
welcome.
Other than that my machine boots and reports from time to time
scheduling while atomic
and
sleeping function called from invalid context at kernel/rtmutex.c:683
Both errors probably happen because some spin_locks need to be converted
to raw_spin_locks. Will look later.
I provide this uncooked state to prevent duplicate work, so please
excuse the bad code and commit history. If it upsets you, please send
patches :-)
Best regards
Uwe
[1] if trace_test_buffer sets count = 0 or returns != 0 in
kernel/trace/trace_selftest.c:440, the code flow is:
tracing_start()
goto out;
...
out:
trace->reset(tr);
tracing_start();
I think the last tracing_start is wrong, but I didn't check deeply.

I'm just attaching the whole dmesg output as that might provide more
clues...
In short, two types, one BUG and another WARNING:
BUG: sleeping function called from invalid context at
kernel/rtmutex.c:683
WARNING: at fs/sysfs/group.c:138 sysfs_remove_group+0x3e/0xa8()
Thanks again for all the hard work!
(and looking forward to the next rt patch!)

I still have this problem. I digged into irqsoff without finding the reason.
Looking at trace_selftest_startup_irqsoff I saw that
trace_buffer_lock_reserve is called thrice successfully.
Steven (or someone else of course), do you can give me a hint?

Up to now I didn't try to do much with my system, but just booting
doesn't yield such BUGs or Warnings anymore.

- disable -rt conflicting config options
- hotplug cpu fixes (peterz)
- slab/pagealloc lock breaks (peterz / tglx)
- sigqueue caching for -rt tasks
- posixtimer thread avoid useless wakeups
- various build fixes (mingo, frank ....)
- lots of tracer updates from -tip (check the tip git logs)
The outstanding improvement is the slab/pagealloc change which breaks
and splits locking and brought down worst case latencies in
problematic use cases from >500us to <100us.
As a side note:
There seems to be a wide spread underestimation of the problem spots
exposed by preempt-rt. The usual shrug off answer is:
"I don't care about -rt. Come back if you can expose the same
problem in the mainline kernel."
This is a fundamentally wrong answer.
preempt-rt mostly exposes existing latency spots and magnifies
them
Reducing latencies in -rt by a factor 5 will be not that
prominent in a non-rt setup, but the problematic code area
will still produce measureable latency problems.
I'm well aware of the tradeoff between determinitic behaviour and
throughput, but problematic spots (e.g. lock contentions) hurt
both.
So can we please put down the stupid "I don't care about -rt"
attitudes and accept that we have to think about the mutual
benefits of deterministic and throughput aspects without hurting
each other ?

Do you have a time estimate for -rt2/ARM support, and is there
anything that can be done to help (testing, etc).

- tracing fixes for ARM (Uwe Kleine-Koenig)
The support for ARM/PowerPC has only been lightly tested. It might
crash and burn your system, make your hair curl, frigthen your cat and
give you sleepless nights. You have been warned !
On PowerPC watch out for the following warning:
__do_IRQ called for irq X. PREEMPT_RT will crash your system soon.
__do_IRQ is deprecated and -rt does not support it anymore. Most of
the PowerPC subarchitectures do not longer use it, but you might be
unlucky and hit one of the remaining users. RT will spit out the
message above and then do what it said. :)

More testing and an Oops that prevents booting... maybe unrelated to rt?
(this is with 2.6.29-rc8 plus additional patches from Fedora's koji
build 61 for fc10). First time my laptop does not boot with the new
kernels on a long time.
See below.

perhaps try excluding the microcode module for now - maybe it messed

does any of the Fedora patches you have applied involve wireless

Strangely enough rc8-rt1 boots (almost). _Exact_ same build with the
exception of the change from rt1 -> rt2.
Haldaemon does not start on boot (fails), if I login as root and start
the haldaemon service manually it starts. And then things seem to work
fine (I'm writing this email from that machine). Still investigating...

First problem was due to old firmware for the iwl3945 hardware. I
updated to the latest and hal started fine (this is on fc9).
Now another one related to xorg/drm...
Oh well...

Scratch that, I had an old version of xorg/drm installed in this
particular machine and the new kernel did not like it. Seems to boot
fine now... sorry for the noise.

No problem :-)
I'm wondering, do you have any theory about how the old firmware
cause that weird NX-fault kernel crash? For a few minutes i took it
for an x86 crash.
Ingo
Fernando Lopez-Lezcano
Sorry, no theories at all - I would have to be a kernel guru for that. I
was surprised the whole thing went away with the firmware upgrade (I saw
some message in /var/log/messages telling me the firmware was old) - it
did seem like something more serious.
I hit another problem. On a quad code intel machine here at home there
is a problem during shutdown. The final shutdown dies with a traceback
(something like "rc0 was killed by SIGSEGV" or similar words at the very
end). Then I have to push the power button for x+ seconds to force a
power off.
Should I post a picture of the screen as it is at that point, or just
send that to you and Thomas?
-- Fernando
Ingo Molnar
any kernel stack dump in that?
You could try to do this before shutting down:
echo 1 > /proc/sys/kernel/print-fatal-signals
dmesg -n 8
that way there's a (hopefully helpful) stack dump done of the
SIGSEGV itself.

Hmm. Do you have CONFIG_HAVE_DYNAMIC_FTRACE=y in your config ? If yes,
can you please disable it ?

That'd be very helpful.

Hi,
It doesn't seem to be available (404).
But I can see a 2.6.29-rc8-rt4.bz2 downloadable.
Thanks.

This is a channel log from #linux-rt
19:57 < clark|w> tglx, just how small was the -rt3 window (which I hit btw)?
19:58 < tglx> you mean how long -rt3 was up on the web ?
19:58 < clark|w> yeah
19:58 < tglx> half an hour or so
19:59 < clark|w> because I got it, built/booted it (64-bit) and was running it
up til thismorning when I saw that you'd released -rt4 :)
19:59 < tglx> 64bit was fine
19:59 < tglx> I fixed a 32bit PAE bug in -rt2 and when I pushed out -rt3 I did
not notice that half of the fix was lost
20:00 < tglx> so I zapped it and pushed out rt4
20:00 < clark|w> cool
20:00 < clark|w> good think I'm 64bit clean :)
20:00 < tglx> but I was too tired to send out another mail
Just FYI
Uwe

The crash happens in alternatives_smp_switch(). Can you check whether
adding "noreplace-smp" to the kernel command line helps ? I boot your
config on my own T61. Hopefully I can reproduce.
