Please test with the following kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
In this newer kernel code is the fix to enlarge unfenced alignments that
I mentioned in the previous comment, which appears to be a problem
specific to i915/i945. If that kernel makes this lockup bug go away,
then we can investigate extracting and backporting it. If not and we can
rule out that fix for this issue, upstream (Chris Wilson) will
investigate further.
** Changed in: xserver-xorg-video-intel (Ubuntu)
Status: Confirmed => Incomplete
