Forwarding this bug from Ubuntu reporter Zhmak: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/740786 [Problem] GPU lockup on i915gm, with kernel that includes commit b5b5ac2d patched in. See also bug #35516 which I think is the same issue, closed perhaps too optimistically? [Original Description] Sometimes getting "melting snow" effect on screen before login screen. in dmesg: [ 31.240026] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 31.241477] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 1742 at 1740, next 1743) [ 31.243307] [drm:i915_reset] *ERROR* Failed to reset chip. Also getting flickering trash in new pop-up windows while its opening in classic gnome desktop mode. Opening same pop-up again looks fine.

Created attachment 44816 [details] [review] Round up GTT allocations to next even tile Bryce, are you still testing with the "round up to fence size"? If not the attached which should fix the i8xx issues might help here.
I'm seeing a very similar lockup with ESR: 0x00000001 and IPEHR: 0x02000011... whatever those mean. :) But I tried the attached patch against Gentoo's 2.6.38 and it's still happening, I'm afraid. One of the Ubuntu bugs mentioned Chrome. That's where I see it too and yet I managed to play Black & White under Wine for a good hour or so without problems. 2.6.37.4 seems fine.
Ok, this is a slight variation on the theme (only in that the batch contains more than the single 3D blit of the others), but the killer operation looks the semantically the same. *** This bug has been marked as a duplicate of bug 34014 ***
