3.1-rc1-git9: Reported regressions 2.6.39 -> 3.0

3.1-rc1-git9: Reported regressions 2.6.39 -> 3.0

[Rafael J. Wysocki]

[NOTE:
 We already have a bug entry for tracking regressions from 3.0:

 http://bugzilla.kernel.org/show_bug.cgi?id=40982

 but there are no reports linked to it, mostly because Maciej is on vacation,
 but also because the frequency of reporting regressions has been low
 recently.  So, if you're seeing a regression from 3.0, please let us know.]

This message contains a list of some post-2.6.39 regressions introduced before
3.0, for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved post-2.6.39 regressions, please let us know
either and we'll add them to the list.  Also, please let us 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.

I am not sure of the correct procedure, but the issue was fixed just
before the 3.0 release and the ticket is currently in the RESOLVED state.
Should I change it to closed?

Even if you suspect hardware problems, it's best to CC maintainers.
It's unfortunate that you didn't include full dmesg because there
might have been more clues on what's going on.

The crash itself was pretty random and the machine was half crippled.
That's the best I can do in that circumstance.

How did you capture the oops? Did you try netconsole? There's
documentation of it in Documentation/networking/netconsole.txt and
this article explains how to set it up:

Just paste the sha1 of the commit that fixed it into the bugzilla and
switch it to 'closed/code fix'.

The bugzilla report claims that this commit fixes the regression:

http://git.kernel.org/?p=virt/kvm/kvm.git;a=commitdiff;h=e72ef590a3ef3047f6ed5bcb8808a9734f6c4b32

The commit, however, is not in mainline nor does it seem to be tagged
for -stable.

There's no evidence in the bug report that the ath9k maintainers know
about this. I'm CC'ing Luis and Jouni.

This one was due the the CPU's idea of the current time getting way
out of sync (as in more than a minute's worth of disagreement, which is
pretty impressive when you think about it).  So what happened is that
one CPU decided that the current grace period was a full minute old
immediately, and thus started screaming piteously.  John Stultz provided
a configuration workaround, and he and Thomas Gleixner would be working
out the long-term fix.

Hello Rafael,

the regression has been solved for 3.0 by disabling the problematic code here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=f483d3923dc3a6394c483e28ccb3fe700bdf399e

When the new commandline argument 'pci=realloc' is not set (which is the
default) the buggy code is disabled.

Therefore this bug can be closed on the 2.6.39 -> 3.0 regression list.

Thanks,
Oliver

Most likely kvm.git got that commit from Linus - I don't think the fix 
came from kvm.git.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Hm ok. But the tree tested by the reporter is contained in kvm/master
and kvm/next and not in Linus tree. 

Anyhow, Rafael did ask the correct question on the bug to resolve
this. :)

RE: [Bug #39412] Win Vista and Win2K8 guests' network breaks down

Hi folks,
I'm the reporter for the bug. Sorry for being late cause I was busy with other stuff.
I only test upstream of Avi's kvm.git and qemu-kvm.git.
>From my test, my automatic test cases for Win Vista and Win2k8 failed at that time. And I also tried this manually, and met the same issue. So I'm sure this was a bug at that time.
Sorry, I don't think I have time to bisect which commit or patch introduced and fixed this issue very accurately.
I can provide some info.

It seems the bug has been completely fixed in kernel 3.0.3. At least 
I don’t have any problems anymore. So I think the bug can be closed.

Thank you all for helping and fixing the bug.

Shade and sweet water!

I must have forgotten people were actually triggering this on 3.0. Feel
free to tell gregkh to include those two patches in his next 3.0-stable
lineup.
