This one was a userspace bug it seems.

Yes, Debian often fixes our bugs on time! ;-)

This one is fixed via a patch that is queued to be merged into 2.6.33. Is submitted
for stable as well.

I believe this problem to be the same as the previous one, and the fix indicated above
should fix this as well.
Note however that the submitter had presumably unrelated issues that caused him not to
be able to validate the workaround of disabling powersaving.

Hi,
The bug is present on 2.6.32 and subsequent versions (2.6.32.1, 2.6.32.2).
It has been resolved as of 2.6.33-rc1.

Yes, I saw this regression and there is a patch to handle this, but it
kind of disables sync at all. Jens Axboe, who introduced per-bdi
writeback patches, did not yet reply.

Yes, FPDMA auto-activate optimization was introduced for AHCI in
2.6.32 and it appears it doesn't work quite right with either the
reporter's AHCI controller or their drive. I believe they were going
to try the drive with an Intel controller to see if it worked there.
It would be useful if we could get other success/failure reports with
either the particular drive, WDC WD800ADFS-75SLR2 (or at least other
WD Raptor ADFS-series) on other AHCI controllers, or other drives
which have AA support on the MCP7A chipset. One of the two needs
blacklisting for AA support. I'm leaning towards the controller since
other WD drives with AA support work fine on Intel AHCI.

Specified commit would break the pnp driver which is using
driver->shutdown.
Could you test this (untested) patch?

[PATCH] rtc_cmos: convert shutdown to new pnp_driver->shutdown
commit abd6633c67925f90775bb74755f9c547e30f1f20 adds shutdown method
to bus driver blindly. With it, driver->shutdown is invalid anymore.
Use pnp_driver->shutdown instead.

Hello Rafael,
I can confirm the bug is still present. I've also created kernel
bugzilla account so I can track the status and provide further
testing/feedback.
Thanks for Your interest.

If this is what I think, then it's a "regular" bug, not a regression.

This seems to be related to commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff.
It clears dev->state_saved blindly, but pci_pm_resume() calls
pci_restore_standard_config() before pm->resume() (by probably
historical reason).
So, I guess it became the cause of restore regression before changing
PCI power state. It might be better to revert
4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff for now, until changing pci
generic stuff.
Thanks.

I plan on testing 2.6.32.2 later today in hopes that some of the IOMMU
changes will have done something in regards to this.

#14627 and this bug are duplicates.
Bugs #14900, and #14728 look very suspiciously like they might be the
same thing as well.
I would be interested to see if commenting out:
'#define USE_PCI_DMA_API 1' in drivers/char/agp/intel-agp.c fixes the
problem for those bugs as well.
I suspect that some better run time checking is called for here.

IMHO this bug might be considered as fixed by updating a userspace tool
(KNetworkManager) - unless somebody wants to seek for the exact reason...

For me (I am the reporter) the problem was solved by upgrading a userspace
tool, so I think the bug filed against the kernel can be closed marking
that this was not really a kernel bug.

Need to boot 2.6.32.2 with "nomodeset" option to make the above bug go
away. Without "nomodeset" option, i.e. the default for intel kms, the
system behaves very strangley/sluggish under 2.6.32.2.
So yes, please still list this bug.

The other way around. pci_restore_standard_config() is the new thing and the
pci_restore_state() in ->resume() is supposed to be unnecessary. Unfortunately
in this case the restoration of PCI config registers in
pci_restore_standard_config() doesn't work.
I'd like to understand the reason, but temporarily we can just set
pdev->state_saved to 1 in sky2_resume(), as proposed in the bug entry.

In fact 4b77b0a2ba27 is a bug fix so I'm afraid it won't be safe to revert it.

Yes, let's hope author(s) of KNetworkManager would let us know if they
had to change it because of the kernel error.

Is it known how it was fixed in 2.6.33-rc1 or do you just see that the bug is
not present in there any more?

Sure. However, it might not be only sky2. Well, anyway, another likely
one is - restore() should be called after pci_pm_default_resume()?

Hi,
Like I reported at [1], I strongly believe this was the same as bug as
#12794, which was resolved by a patch resulting from my feedback and
Jussi Kivilinna's work. After I enabled memory debug like suggested on
bug #14436, everything pointed in the direction of that bug.
The issue was solved after applying Jussi's patch. That patch has been
commited to the mainline kernel and I can assert that since then the
bug didn't occur again.

That's correct. It more likely is a chipset issue.

No, because we want the PCI standard config spaces to be restored before
the device interrupts are enabled to avoid intermittent resume failures related
to interrupt mishandling.
That's why it is important to understand the nature of the sky2 failure here.

Um..., it was 0xff, so, I thought the config space is not working. On
that system, the device is not affected by acpi's _DSW or _PSW?
Well, ok. If someone is working for it, that's enough good to me.

I don't think it is, but of course I'm not sure.

This regression along with the associated one:

Any chance to get this into -stable? Since it seems it got only merged
after 2.6.32.

Since pohmelfs isn't tied to a single block device, it needs to setup a
backing dev like nfs/btrfs/etc do. Here's a completely untested patch.

[PATCH] rtc_cmos: convert shutdown to new pnp_driver->shutdown
commit abd6633c67925f90775bb74755f9c547e30f1f20 adds shutdown method
to bus driver blindly. With it, driver->shutdown is invalid anymore.
Use pnp_driver->shutdown instead.

This bug is fixed in mainline with commit
70d57139f932b9ca21026253d02af71cf53d764a. This patch has also been backported to
2.6.32.2. The status of the Bugzilla entry has been changed to "CLOSED with CODE
FIX".

The machine in question has been up continuously (though not under heavy
load) since it was rebooted after the reported failure. it has even
withstood additional mpd index updates, all running the same kernel it
crashed with before.
So i can't say that the problem is resolved, but i haven't replicated it
either. Wish i had more interesting details to report.
Thanks for doing followup/triage like this. it's an important (and too
often neglected) part of software development.

the problem was gone after the latest Debian lenny and etch upgrades
(one of libexpat1, libltdl3, libpq4/5 does the fix). I think that the
kernel change which came with e11c675ede0d42a405ae595528bf0b29ce1ae56f
is now supported in Debian, so it is no longer a kernel issue.
Please remove the error from the regression list.
Thanks,
Andreas

I'm going to close it as "unreprodicible", then. Please reopen if you're able
to reproduce it after all.

Well, you're welcome. :-)

Thanks, closing.

Hi Jens.
Thanks a lot for your patch, it looks good, but I'm not able to check it
right now - its new year holidays here, that's also why reply is too late :)
I will try it in a week and report back.

Hi.
Sorry, it took really long to catch all the things around, but it is
better than never.
History says that commit which introduced per-bdi writeback broke
pohmelfs, since it does not have backing store device and did not fill
appropriate superblock entry, which lead to crash on umoount.
Jens provided a patch below, which I tested to fix the problem.
There is a problem though, when all writes happend before umount,
but did net yet written back to storage, get lost. I can not say whether
this happens because of per-bdi writeback (it should not I think), but
that's what happens.
Albeit being a bug, it will not be fixed :)
The reason is simple, new backing storage for POHMELFS (a distributed
hash table called elliptics network) is essentially ready and I start
working on porting POHMELFS to it, which means all its bugs will be
fixed there^W^Werased and written from scratch.
Jens, thanks a lot for you patch, Greg please pull it up.
If you did not find it or can not extract from the reply, I will resend.
Thanks everyone!

Thanks, I've linked the Jens' patch to the bugzilla entry and marked the
bug as resolved.

Greg, you can add mine as well, I didn't provide one in the original
posting since it was just a test patch.
