Intel 945 - X crashes with "[drm:i915_hangcheck_elapsed]" [lucid]

[YenTheFirst]

Binary package hint: xorg

In certain conditions, my X session crashes entirely, and I'm dropped to a regular terminal on tty1 or tty2.
Crashes seem to happen at random, but I seem to be able to reproduce it by opening an mp4 video in google-chrome.

dmesg shows the error "[drm:i915_hangcheck_elapsed]"

Is any more information needed for this bug?
It's starting to affect me about every other day, now.

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 . Please test the latest v3.3 kernel[1] (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 3.3-rc2 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.3-rc2'.

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

Thanks in advance.

The laptop that I filed this bug against hasn't had Lucid installed for a while now. Would a live boot be sufficient for testing?
