Bug Description

This bug seems to be particular to Sandybridge hardware. The IPEHR values seem to vary from freeze to freeze, but seem to not be random. The value 0x68b0000 has been seen in a few different reports by different people, along with 0x78170003 and one or two other codes.

Here is an example sequence from one reporter on a particular system:
#733206 (IPEHR: 0x78170003)
#733208 (IPEHR: 0x680b0000)
#733209 (IPEHR: 0x78170003)
#733324 (IPEHR: 0x680b0000)

His description: "The GPU lockups really soon. The time between the login and the lockup is between a few seconds and a few minutes. Opening Nautilus and trying to do something there is a guarantee for catching a lockup."

Thank you for following up with a new bug report.

This apport capture is a lot more detailed than bug 715122; in fact with that bug it's not really evident what went wrong (the error codes are all 0's). But this one shows that there's been a divide error. There is no reason not to think it's the same as the previous lockup, so I'm duping the previous one to this one.

Since it sounds like you experience this crash multiple times, can you speculate what actions or activities seem to trigger it the most? A divide-by-zero error seems like something which would have a way to trigger it.

Hmm, it's interesting that IPEHR varies from bug to bug, but otherwise the error codes look the same.

Thanks for filing multiple reports; it gives us extra data points and demonstrates it as an ongoing issue. I think you've given us enough data though, so I think you can hold off filing more bug reports about this freeze issue until bug 718870 is resolved or until we need more testing.

It's likely this lockup is due to a bug in the kernel, and given the newness of sandybridge it is not unlikely that a kernel update will bring a fix from upstream. So please keep an eye out for if the bug goes away after an update and follow up here.

Meanwhile, I think the next step is to forward this bug report upstream for further attention.

This bug is probably a kernel issue. I don't get this crash with the drm-intel-next kernel (version 2.6.38-997.201103081433).

This bug is fixed in the vanilla kernel 2.6.38 (taken from the kernel PPA). Can the others test the vanilla kernel [1] too and report back if this kernel fixes the issue too?

Maybe I have another bug, but the kernels mentioned in #4 and #5 do not behave any better.
Whole machine hangs during the first minute after logon to KDE. With those two
kernels it's so hanged I can't switch terminal and so can't see the error message.
Even SysRq doesn't work.

Latest kernel I have not crashing or hanging is 2.6.37-02063701-generic.
2.6.38-1-generic (based on rc2 I think) is the next one I have which started to show the problem.

Thanks for confirming this bug is resolved by an updated kernel. That kernel version should be released to ubuntu shortly, so we can close out this bug at that time.

bdrung, I gather that the kernel team has now baselined the 2.6.38 kernel, which corresponds to the one you believe is fixed from comment #5 - can you confirm that the issue is indeed gone for you? If so, this bug report can be closed out now.

Yes, this issue is gone with the 2.6.38-7 kernel.

My machine had the same behavior described in comment #5, but now I am running 2.6.38-7 without any crash in days :)

I wish I could say the issue is gone for me too. But I can't. It just doesn't work.
Whole computer hangs so I cannot get any messages too. Cannot log in over network,
sysrq doesn't work.

Anyway, most probably it is another bug, we can close this report. I won't be reporting
a new one though (because I really can't get any useful information on this one, except
that linux-image-2.6.37-02063701-generic is the latest one which doesn't hang).

For the record, this still affects Maverick installs; to get around this, you'll need an updated 2.6.38 kernel. And, if you want working GPU acceleration, see the PPAs suggested at http://ubuntuforums.org/showpost.php?p=10358709&postcount=3
