[i915] x200s locks up hard about once an hour

[Chris Halse Rogers]

Release of Ubuntu: Precise

This is somewhat of a placeholder bug; I haven't got any useful logs out of the machine yet, as it locks up hard - doesn't respond to the network, and none of the logs make it to disc.

With fairly high frequency (~1/hr, sometimes more) the system locks up. This sometimes, but not always, seems to coincide with hitting alt-tab in Unity3D.

I'll try to grab some logs and investigate further.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This doesn't appear to affect the 3.2.0-2-generic kernel; I haven't yet tried 3.2.0-3-generic nor the newer kernel upload.

[Robert Hooker (sarvatt)]

Can you give this kernel a shot? it's the latest with eb1711bb94991e93669c5a1b5f84f11be2d51ea1 reverted which has been reported to cause this other places

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

This is a pretty nasty regression from the recent 3.2.0-4 kernel upload, so I'm targetting this to precise. The upstream bug discussion sounds promising.

Seems to be the same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/903010 and fixed in 3.2-rc6 by reverting the above commit
