o.k. just pulled the latest to see, and
the warning message is there.
so yes this bug report should be open
until this is fixed.

(still need to go through and revert commits,
to see if I can find exactly where).
So yes this should still be open.

This one has me a bit dazed i.g. after looking into the issue
I did find a workaround(keep in mind it's not pretty),
by commenting out set_fixmap_nocache and
init_ohci1394_reset_and_init_dma.
(by doing so I was able to load both machines and
execute early debugging in case a problem occurs).
Now as to what might be happening, after going through as
much as I can comprehend the only thing in mind was
reading fixmap.h the comments are stating that vsyscalls
only covers 32bit, and that there needs to be another set
for 64, leading me to believe that this is what I might be hitting.
(my system is pure64, taking in no 32bit at all).
At this point I think I need somebody to give me some info on this,
and if the 64bit issue mentioned above is the case, then we can probably
close this and leave it up to the x86_64 builders to create a 64bit
call for this whenever they get to it.(main thing is I'm able to
run dma early in case of an emergency).

This looks like an input core problem, as the evdev module was just
loaded and died.
Any input developers have any ideas?

Um, this was marked as resolved, until you reopened it and then reset
the state to New. Why did you do this?
It's fixed in mainline as of commit d4da6c9 when Linus reverted commit
d0646f7. Users could still see it if they mount a file system with -o
journal_checksum, but (a) it's no longer the default, and (b)
corruption if you use the non-default journal_checksum mount option is
not a regression.
We have fixes to make journal_checksum safe queued for 2.6.33, but the
revert fixes the regression problem.

This isn't technically a regression, since the warning is simply
complaining about something that apparently ext4 has been doing for a
long time, which is that it allocates some very large order data
buffers. So the change referenced simply printed a warning message
that complained about the fact.
The actual problem will be fixed in 2.6.32, as we no longer allocate
the big data buffers at mount time.

Anything I should/could do to narrow it down a bit (apart from
bisecting?).

Umm, I looked through the changes between -rc6 and 7 but nothing jumped
out at me... You don't happen to have any local changes in your tree?

Looks like a suspend bug, not an irq bug. The new warnings in the
suspend/resume code might have triggered an old bug in that particular
driver.

We can see the mm_fault_error in stack trace.
I guess it's from returning VM_FAULT_OOM of any driver.
As I know, It happens very rarely. Norbert, right?
In addition, I don't see the any similar report.
So I think It would be better to ignore this bug
until we can meet similar report again.

I asked Greg to re-open for a while to track other issues with
various Huawei modems. However, it appears that most of them would
be tricky to workaround in the kernel and are fixed by FW updates
(though updating those modem FW can be non trivial).
I'll leave it open for a little while see how things go on the
corresponding ubuntu bug, and if things settle, we can then close it,
in the meantime, you can remove it from your list of regressions.
Cheers,
Ben.

Agreed. It is so hard to reproduce, and might be some other reason for
that.

Yes definitely.

Agreed, please close or whatever.
In case I find a method to reproduce it more easily I will come back to
you.

It is still valid. We haven't yet been able to verify if it is either a
hardware problem (working with the adaptec folks to sort that out) or a
kernel problem (working with you to find that out ;). Kernel 2.6.30, as
already said, seems to think everything is fine, so it really might be a
regression.

It's mostly gone. It still happens for like 1/4s once per 6hours but jbarnes
asked me to fill separate bug for that and gave such patch for testing (see below).
So far haven't seen 1/4s problem with this patch applied.

I wasn't quite sure what the status was, because there was some activity in the

That's quite possible, although that's rather core code than a driver.
Anyway, I haven't been able to find the bug in there so far.

irqrouter_resume() seems to be solely ACPI code. I have not seen where
it might reenable interrupts, but ACPI folks might shed some light on
that.

Yeah, the actual regression had been resolved (by changing the
default), but the root cause was due to the fact that not enough
people had done proper power-fail testing for the journal_checksum,
even though the code had been in the kernel for a very long time. The
discussion afterwards was focused around fixing those problems so we
could make journal_checksum be the default at some point in the future.

Yanmin, could you please update me on the status of these regressions?
Mike seems to have done a lot to address issues while I was out, and
while I (hopefully) did read all resulting email, I must admit to
loosing track of where we stand.

I have been looking through the changes and I really don't see anything

We're going to need more information to diagnose this.
And linux-ide should have been at least CC:'d from the very
beginning.
From what I can discern the problem is introduced somewhere between
2.6.27 and 2.6.31, you have a Serverworks CSB5 and primarily the issue
is that attaching or detaching your CD-ROM driver influences whether
both of your disks are properly detected. Correct?
You seem to have played around with using the IDE layer vs. the
ATA layer. Can you see any difference in behavior if you try
using just the IDE layer vs. just the ATA layer with the 2.6.31
kernel?
Thanks.

On core2 arch machines, hackbench regression disappears and there is much
improvement instead of regression.
On Nehalem machine, no big change, comparing with 2.6.31.
On Itanium machines (2 sockets or 4 sockets), the regression become
about 20%. Originally it's 70%.

On core2 arch machines, tbench regression becomes about 4%. Originally, the
regression is about 33%.
On Nehalem, tbench regression is about 4%. Original is 7%.
On Itanium, tbench regression is about 16%. Original is 26%

Mike's patch 1b9508f6831e10 could improve netperf loopback testing.
The latest upstream doesn't merge it yet.

The kinda ugly thing below gives me around a 4% boost for pinned tasks.
Looking around is expensive to fast movers, some cost can be avoided.

Unfortunately, both of these photos only show that MD (block major 9)
device could not be found for root.
For either ATA or IDE, we would need to see full dmesg somehow --
perhaps capturing serial console output? (Documentation/serial-console.txt)

I bet libata fails because CONFIG_BLK_DEV_SD is not enabled. Probably
want to enable CONFIG_BLK_DEV_SR too, for libata CD-ROM support. I
would be interested to see your failing ATA config, with IDE disabled.

Ok, I appended
console=ttyS1,9600 console=tty0
to the kernel command line at lilo after choosing the kernel image and
I get a ton of output. But how to I save the output to a file?

I enabled CONFIG_BLK_DEV_SR. Do you want above test with or without
CONFIG_BLK_DEV_SVWKS (OSB4/CSB5) enabled?

I use minicom and a null modem serial cable. One of minicom's commands
will capture everything sent to the serial port, to a file. Other
options are available. Googling for "linux serial console" found
several useful starting-point links.
The basic idea is to sent console output to a serial port, and then have
some method of reading and capturing the serial port's data.
Another alternative is netconsole (google for "linux netconsole"), which
permits output over the network.

Well, this goes back to David's basic request: IDE-only or ATA-only.
You really, really, really should not to enable both at the same time.
If you are choosing ATA-only (libata), then you should disable
CONFIG_IDE and everything associated with CONFIG_IDE, including
CONFIG_BLK_DEV_SVWKS.
libata will want something like
CONFIG_ATA
CONFIG_ATA_VERBOSE_ERROR <-- optional, but helpful
CONFIG_PATA_SERVERWORKS
CONFIG_SCSI
CONFIG_SCSI_LOGGING <-- ditto
CONFIG_SCSI_CONSTANTS <-- ditto
CONFIG_BLK_DEV_SD
CONFIG_BLK_DEV_SR <-- required only for CD-ROM support

Ok, I will try to look into this.

I find it a bit irritating, that CONFIG_IDE is mentioned as ATA in
make menuconfig. But I'm trying to understand your point.
> You really, really, really should not to enable both at the same time.
I recompiled the kernel only with below settings all enabled.

I disabled CONFIG_IDE this time.

Recompiled with above enabled. And indeed: It worked. Booting as normal.
Thank you for the detailed instructions.

Sage, any updates on this? What was the last kernel version where you
weren't having this problem? Sounds like you can't mount any ext3
file systems at all?

This is a btrfs bug and is fixed. I've updated the bugzilla.

Thanks! I remember seeing that but I didn't connect it to this
bugzilla entry.
Just trying to do my part to clear out open regressions after Linus
sent out his pre-thanksgiving grump. :-)

Yup, closed.
Thanks,

I cannot promise whether I find the time to do this :/ One thing I
noticed is that applesmc seems to freak out every now and then on boot
(after the oopses). Only on this macbook pro.

PS: I don't have this oops on a desktop machine either.
