2.6.29-rc1: Reported regressions from 2.6.28

2.6.29-rc1: Reported regressions from 2.6.28

[Rafael J. Wysocki]

[Notes:
* 2.6.29-rc1 is out so it's time for a regressions report.  At the moment there
  are not too many regressions from 2.6.28 listed.
* We've got quite a number of regressions from 2.6.27 reported against 2.6.28
  final recently.  For this reason, I'm going to continue reporting regressions
  introduced between 2.6.27 and 2.6.28.
* Regressions 2.6.26 -> 2.6.27 won't be listed any more.  There are only 6 of
  them left and they don't seem to be urgent.
]

This message contains a list of some regressions from 2.6.28, 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 from 2.6.28, 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.

suspend/resume work, otherwise system resumes immediately.

Yes. But, that is a different bug with DRM changes. This fix just unmasks the bug now.

it geve only "System Product Name" ) and use only DMI Board Product Name

The bisection looks invalid. It is unlikely to be this commit at fault. 
Jeff, do you even have that camera?

It is also easy to revert that commit by hand. Just delete the 
unusual_devs entry for it.

I found a nearby commit during bisect, which looks much saner:

This was committed earlier than
a0e280e0f33f6c859a235fb69a875ed8f3420388, and
a0e280e0f33f6c859a235fb69a875ed8f3420388 was the last working kernel
that is able to suspend/resume. Go one before, and suspend/resume
breaks.

Thanks,
Jeff.

Yes, I am aware that this patch fixes one of the many S2R problems in 
2.6.29-rc. Thats why I had 

commit a0e280e0f33f6c859a235fb69a875ed8f3420388
Author: Heiko Carstens <heiko.carstens-tA70FqPdS9bQT0dZR+AlfA@public.gmane.org>
Date:   Wed Jan 7 16:19:46 2009 +0100

    stop_machine/cpu hotplug: fix disable_nonboot_cpus

as an additional patch applied during my bisect.

so you mean a0e280e0f33f6c859a235fb69a875ed8f3420388 seems good, while the 
next step in Linus's tree, 52fefcec97c25b15887e6a9a885ca54e7f7c0928 is 
already broken?

Does 52fefcec97c25b15887e6a9a885ca54e7f7c0928 start working if you do:

  git checkout 52fefcec97c25b15887e6a9a885ca54e7f7c0928
  git revert a0e280e0f33f6c859a235fb69a875ed8f3420388

?

That would implicate a0e280e0f33f6c859a235fb69a875ed8f3420388 + some 
layout/timing problem - which does not trigger for some reason if pure 
a0e280e0f33f6c859a235fb69a875ed8f3420388 is tried.

I guess Jeff, meant the other way around.
Since a0e280e0f33f6c859a235fb69a875ed8f3420388 is a fix for a known S2R 
problem , the earlier patch (before) does of course not work.

ah, okay.

So i suspect that at every bisection point, this should be done:

  git cherry-pick a0e280e0f33f6c859a235fb69a875ed8f3420388

To make sure the bisection finds the secondary breakage too.

(the cherry-pick will fail harmlessly on kernels that have that commit 
already - so it can be done unconditionally at every bisection point.)

I started with the latest git, and did this ...

git bisect start
git bisect bad
git bisect good a0e280e0f33f6c859a235fb69a875ed8f3420388

Everything in-between should have
a0e280e0f33f6c859a235fb69a875ed8f3420388 applied?

not necessarily - if an intermediate tree that is checked happened to have 
been based on some earlier -rc, it might have that bug included. Safest is 
to always cherry-pick that commit. (if it has no dependencies)

Thanks for pointing this out. My bisect was thrown off course because
I didn't "cherry-pick" that commit.

After cherry picking, I ended up with the same commit as was reported by
Christian Borntraeger -- "Regression 2.6.28-git: suspend/resume
failure. git bisected to usb suspend/resume patch".

I was trying to bisect further, but ended up with this strange behavior...

Is this a bug or a feature?

that's a feature - the btrfs history looks like this. You can mark get out 
of that bisection set by doing this:

        git bisect good 34353029534a08e41cfb8be647d734b9ce9ebff8

You bisected into the btrfs development chain. Just say "git bisect good" 
when this happens, and you'll be ok.

[ Unless, of course, you were to be actually trying to bisect a btrfs bug. 
  If so, you'd need to compile btrfs as a module and insert it and do the 
  bisection based on that ]

Ingo, Linus,

Thanks for the explanation. For a while, I was repeating the same
thing just thinking my filesystem was corrupted.

Now, I'm can happily continue to bisect further.

Thanks,

Fixed by reverting a0d4922da2e4ccb0973095d8d29f36f6b1b5f703.
7503bfbae89eba07b46441a5d1594647f6b8ab7d has already been reverted in
the Linus's latest git tree.

Can you please check if the issue goes away when you apply the appended patch
instead of reverting commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703 ?

Confirmed. This commit works. STR still ok.

But now, a different problem. STD "almost" ok. Suspend-to-disk hangs
after counting to 100%. Power-cycle and boot ok able to resume. ...
Again, this is another problem with/without your latest patch. Another
issue is with iwl4965 not able to attach to my hidden AP. Will try to
bisect soon.

Thanks for the patch.

Jeff.

I have doubt about this too, but it's was git bisect zero into. All I
know is a0e280e0f33f6c859a235fb69a875ed8f3420388 is definitely good.

No, I don't have this.

I'm lost reverting this. Right now, I'm just use "git diff" and throw
away everything after a0e280e0f33f6c859a235fb69a875ed8f3420388, and my
system can STD, STR without an problem resuming.

This is a wrong fix, asm/smp.h should only be included when CONFIG_SMP
is defined.

I am still in the process of cleaning non-smp data from asm/smp.h for x86

Attach patch is the solution for the time being

Ingo, can you please put this in urgent queue.

Thanks

I can trigger it too and it is pretty much resolved - false positive 
WARN_ON() triggered by new (but correct) libata usage.

Should be solved by Venki's PAT fixes in tip/x86/urgent:

 0e95c19: x86, pat: fix reserve_memtype() for legacy 1MB range
 74edd61: x86 PAT: remove CPA WARN_ON for zero pte
 e722dc8: x86 PAT: ioremap_wc should take resource_size_t parameter
 b61e53c: x86 PAT: return compatible mapping to remap_pfn_range callers
 e104ba3: x86 PAT: change track_pfn_vma_new to take pgprot_t pointer param
 3cedb0d: x86 PAT: consolidate old memtype new memtype check into a function
 e61304a: x86 PAT: remove PFNMAP type on track_pfn_vma_new() error

Soon to be sent to Linus.

Subject		: No backlight control on Samsung x360

I think this is a common bug on systems with a broken(?) bios, exposing wrong 
driver names. With 2.6.27 it was at least possible to control the backlight 
over the NVID interface.

2.6.29-rc3-git6: Reported regressions from 2.6.28

[Rafael J. Wysocki]

[NOTES:
 * Sorry for the delay, I had to take care of my own bugs first.
 * Some of the bugs below are fixed, but I wasn't able to track the fixes down.
 * There probably are some duplicates (mostly in the DRI area), but I wasn't
   100% sure.]

This message contains a list of some regressions from 2.6.28, 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 from 2.6.28, 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.

Latest linux git pull seems to behave slightly better. Restarting the
interface a few times fixes the problem 70% of the time. The rest of
the time, it can't associate with the AP.

I applied the patch
http://marc.info/?l=linux-wireless&m=123320213115108&w=2 and it seems
better now. One instant of not association out of 20 tries, but
reloading the modules seems to make it work again. So, let's just
close the case?


Here's part of the dmesg. Kernel is 2.6.29-rc5 with patch above applied.

I tested on another AP (WAG200G ), and this one, it's failing to
associate more often. And I noticed that when it does associate, I
don't get these two lines ...

iwlagn: TX Power requested while scanning!
iwlagn: Error sending TX power (-11)



Here's a good run ...
