   fixed, but I didn't have the time to search through all of the histories.
   _Please_ let me know which of them can be closed.

   hash of the fix commit into the Bugzilla entry.]

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

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.

Thanks for the update.

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?

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.

Luís Picciochi

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.

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.

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.

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

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.

Re: [Bug #14742] 2.6.32 new menu idle governor causes very high CPU temp

[Andrew Watts]

All:

Though there has been no activity on this bug since my last comment on 12/7/09, the issue remains unresolved. I have confirmed that the problem occurs only on linux using the new menu idle governor code (69d25870f20c4b2563304f2b79c5300dd60a067e) . The HW performs perfectly well either: (a) in linux with the old idle governor code or (b) under windows XP.

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.

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.

Regards,

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

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.

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.

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.

Re: [Bug #14894] pohmelfs: NULL pointer dereference

[Evgeniy Polyakov]

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!

Greg, you can add mine as well, I didn't provide one in the original

[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.

OK, dropping from the list for now.  Please let me know in case it turns out to

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

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.

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.

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.

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

[Bug #14670] i915: playing video via XVideo extension makes the screen flicker

[Rafael J. Wysocki]

This message has been generated automatically as a part of a report
of regressions introduced between 2.6.31 and 2.6.32.

The following bug entry is on the current list of known regressions
introduced between 2.6.31 and 2.6.32.  Please verify if it still should
be listed and let me know (either way).

Yes, still should be listed.

Problem still exists in 2.6.32.3 and 2.6.33-rc3-00097-g2c1f189, that
contains
this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cda9d05c499093c67b4a376a15009923acc2127a

The above commit removes the render reclock support, that ought to fix a common
kind of problem encountered on i915 hardware, but not on my machine.

Still need to boot with "nomodeset" to have a workable system.

Does this patch prevent the flicker?

No, sorry.

Reverting b42d4c5c6a872815d711e5d51a600f5122c38eee (i.e. the commit I
bisect my problem to) on top of 3c8ad49b015eb115fbd6982f56d530f53cf57f84
(i.e. 2.6.33-rc3-00147-g3c8ad49) make the problem go away.

My changes are:

It should only be called when a client requests the connection status
(e.g. xrandr or the GNOME display applet).

The LVDS state will also be checked at ACPI LID event time, maybe your
platforms is getting spurious LID events?

If not, this bisection really confuses me...

It's not only a bisection, as Thomas says that reverting the commit turned up
by the bisection fixes the problem for him.

how to check how often this function is called and it's duration? is the
function tracer capable of this?

maybe! where can I check this? acpid log file?

Yeah, the function tracer should be able to do it (though I don't know
how to use it offhand, maybe through the perf tool?).  Or you could
just add some DRM_ERROR lines. :)

Yeah or using acpi_listen I think.

I set the function tracer to the function "drm_mode_getconnector":

here is the output, that i captured after I start playing a video with
totem (i.e. the flickering starts):

Any idea why the function "drm_mode_getconnector" is called so many
times?

The call chain seems to be

drm_ioctl ->
drm_mode_getconnector ->
drm_helper_probe_single_connector_modes ->
  intel_crt_detect, intel_hdmi_detect and intel_lvds_detect

acpi lid events seems to correspond to the lid status.

After recompiling the kernel without optimize for size I could use the
function graph tracer and set the function to "intel_lvds_detect".

Here is an example of the output:

 0)   0.365 us    |                up();
 0)   1.092 us    |              }
 0)   1.824 us    |            }
 0)   2.486 us    |          }
 0)   0.376 us    |          kfree();
 0) ! 9759.012 us |        }
 0) ! 9759.813 us |      }
 0) ! 9761.096 us |    }
 0) ! 9764.483 us |  }
 0)               |  intel_lvds_detect() {
 0)               |    acpi_lid_open() {
 0)               |      acpi_evaluate_integer() {
 0)               |        acpi_evaluate_object() {
 0)               |          acpi_os_allocate_zeroed() {
 0)               |            __kmalloc() {
 0)   0.366 us    |              get_slab();
 0)   0.336 us    |              _cond_resched();
 0)   0.396 us    |              memset();
 0)   2.796 us    |            }
 0)   3.447 us    |          }
 0)   0.531 us    |          acpi_ns_validate_handle();

So the call to "intel_lvds_detect" seems to take around 10000us, i.e.
10ms (I guess this is long), thanks to heavy ACPI interpretation.

So the question still is: Why is the drm_ioctl (that in turn calls
intel_lvds_detect) called so often by Xorg?

this one may also be fixed by David's patch if -rc5 doesn't already fix
it.

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!
