xf86-video-intel commit 736b89504a32239a0c7dfb5961c1b8292dd744bd

uxa: Align surface allocations to even tile rows
Align surface sizes to an even number of tile rows to cater for sampler
prefetch. If we read beyond the last page we may catch the PTE in a
state of flux and trigger a GPU hang. Also detected by enabling invalid
PTE access checking.

Title:
[arrandale] GPU lockup IPEHR: 0x02000022
Status in X.org xf86-video-intel:
Incomplete
Status in “linux” package in Ubuntu:
Triaged
Status in “xserver-xorg-video-intel” package in Ubuntu:
Incomplete
Bug description:
These hangs started a few days ago in raring. There is no discernible
trigger, it happens out of the blue. When it happens, the X screen
stays uncorrupted, but totally freezes. The mouse cursor still works.
I can switch to VT1 and work there. Killing my processes and
restarting my session/X.org works up to some degree, but in the
restarted session compiz behaves very erratic (lots of flickering grey
rectangles, and compiz takes 100% CPU), so the only cure is to reboot.
This happens several times a day.
