2.6.33-rc5: Reported regressions 2.6.31 -> 2.6.32
Rafael J. Wysocki
* This is worrisome. Regressions from 2.6.31 are still being reported and we
are not fixing them. Even the ones that have been bisected don't seem to
be taken care of.]
This message contains a list of some regressions introduced between 2.6.31 and
2.6.32, for which there are no fixes in the mainline I know of. If any of them
have been fixed already, please let me know.
If you know of any other unresolved regressions introduced between 2.6.31
and 2.6.32, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.
Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

yeah I'm still seeing this during boot.
As of looking at this, been tied up with another
issue and totally forgot. next week I'll be away
for a week, and during that period I can try and look at this
since I might be hanging around at times.
(and wont be side tracked with the other issue I was looking at);
So yeah please keep it open, and hopefully somebody
see's what is happening and maybe has a solution, or
by chance maybe I can figure something.

It's a confirmed regression. Waiting on some lspci -nn output from the
reporter. However, for now, disabling auto-activate optimization on
all NVIDIA AHCIs may be the easiest option.

Boulan, Can you please help our debugging?
can you disable following config option at once?
1. CONFIG_DRM_I915
2. CONFIG_RELAY
3. CONFIG_MSPEC
4. VIDEOBUF_DMA_SG
I mean
- if anyone return VM_FAULT_OOM, this issue occur.
- very few subsys can return VM_FAULT_OOM in their own fault handler.
- I hope investigate this is core mm issue or not.
(unfortunatelly, I haven't find any dubious recent mm change..)
Thanks.

Hello,
Sorry for the lack of input about this issue. I currently only have remote
access to the machine for which i had this problem, and i'm not confident
with rebooting into potentially broken kernels. That's why i haven't done any
more tests yet..
I will try to reproduce the issue on another machine first, and if i that does
not work i will find a way to test as you suggest.
Also, I have seen in the lkml archives that someone else seems to have the
same problem:
OOM-Killer kills too much with 2.6.32.2
From: Roman Jarosz
Date: Thu Jan 14 2010 - 08:13:36 EST
As i can't have his email from the web archives, could you plase CC: him on
this thread? Maybe he could also help with some tests.
Regards,
Arnaud

FWIW, I might have seen this on my Macbook as well (screen went blank
but I didn't check the logs). I think I managed to unblank the screen
by hitting the "increase brightness" key. But as you say, the bug
doesn't trigger very often and I have no idea how to reproduce it at
will.

I have seen it too on my lenovo T60 with 2.6.32.2. It happens to me
frequently and has become famous as "coffee bug" in my colleagues.
Every morning when I goto office and after putting my laptop on
docking station go for coffee. Once I come back the laptop screen goes
blank, but haven't been able to manage how to get screen back. Only
option is hard reboot. This happens almost every once in two three
days.
Let me know what information/logs I can provide to help debug this.
BTW I normally suspend my laptop at home and then resume it in office
(if that matters).

I don't think it's fixed, I haven't seen the Arjan's patch anywhere close to
the mainline.
Arjan, perhaps send it directly to Linus, please (unless it's already waiting
somewhere for merging)?

I sent it to Len and Andrew (Len as maintainer, Andrew as maintainer of

Well, Andrew, do you have the patch at http://patchwork.kernel.org/patch/71962/
in your queue? It's a regression fix.

The problem still exist I'm using kernel version 2.6.32.6 now.
I have one more observation:
After the reboot, when the NIC is not working, both leds are on. Not
blinking, they light all the time, even if I remove the plug.

Hi, Marc,
Sorry, I don't really understand your description of the problem, your mean
your ssh hangs on socket PF_INET6 for 30 seconds?
Have you enabled CONFIG_DETECT_SOFTLOCKUP for your kernel?
If not, please do it.
Thanks.

Yes, this is a separate issue the cause of which I've informed Jesse

should still be open.

Ought to be fixed by:
8f06d7e: perf timechart: Use tid not pid for COMM change
But i'd like Arjan to confirm this before we can strike this from the list of

Any news on this one Arnd? Does i915.powersave=0 still fix it? If so
the bug David found and fixed may have an effect. Apparently the
hardware wasn't automatically disabling self-refresh mode when multiple
pipes were active (though maybe you didn't have this config?), which
could definitely cause problems.

Yes, this is almost certainly our userspace driver sending the GPU into a
spin. And no, we haven't identified the cause yet, there have a been a lot
of conflicting reports and guesswork, with very little information.

Still see this error with -rc5. But I guess this is very likely an
ACPI/BIOS error. I have an Acer 1810T (1410T in US of A) with BIOS
version 3302. Can someone with the same hardware but different (i.e.
newer BIOS version - version 3303) confirm this bug?
When the flickering occurs, switching VTs back and forth makes the
problem go away!

I had half of it, as
acpi-add-the-hp-pavilion-zv5000-to-the-power-dmi-table.patch. Updated.
From: Arjan van de Ven <ar...@linux.intel.com>
Since the rewrite of the CPU idle governor in 2.6.32, two laptops have
surfaced where the BIOS advertises a C2 power state, but for some reason
this state is not functioning (as verified in both cases by powertop
before the patch in .32).
The old governor had the accidental behavior that if a non-working state
was chosen too many times, it would end up falling back to C1. The new
governor works differently and this accidental behavior is no longer
there; the result is a high temperature on these two machines.
This patch adds these 2 machines to the DMI table for C state anomalies;
by just not using C2 both these machines are better off (the TSC can be
used instead of the pm timer, giving a performance boost for example).

No, it hangs on socket PF_INET6 indefinetely (max time I waited was
like ten minutes), ignoring SIGTERM while hanging. This does only
happen if the sshd is started within seconds of the ipv6 module being
loaded (or the Interface being brought up), so I guess that the kernel
needs to be in a state where it already thinks that it has IPv6 but
hasn't completed autoconfiguration yet.
To obtain an strace, I had to use timeout --signal=9 30. The
virtualbox process this happens inside takes all host CPU while the
ssh process hangs.
> Have you enabled CONFIG_DETECT_SOFTLOCKUP for your kernel?
yes, that's enabled.
