Created attachment 50183 [details] i915_error_state after X restart All versions are from the xorg-edgers PPA packages I installed: Distribution: Ubuntu 11.04 amd64 kernel: 3.0.0 libdrm: 2.4.6+git20110808.2acaf160 mesa: 7.12.0~git20110811.9cd64ec3 DDX (xserver-xorg-video-intel): 2:2.15.901+git20110808.f4bbbd1d Xorg: 2:1.10.2.902+git20110708+server-1.10-branch.bc3c539e I hit this trying the Linux demo for Amnesia: The Dark Descent: http://www.amnesiagame.com/#demo I started it at its lowest settings in windowed, 640x480 mode. As soon as it starts trying to render the start-screen's background scene, the desktop session/window manager starts going crazy, as the window decorations turn white or disappear, as does the taskbar/shell at the top and bottom of the screen. (I'm running the 'Ubuntu Classic' session, so it was probably compiz.) Nothing was responding to my clicks, my Alt+F4s, or my Ctrl+Cs (I launched Amnesia from gnome-terminal -- the "^C" would appear but nothing happened). I VT-switched with Ctrl+Alt+F1 and back again, and it threw me back to the gnome login screen. After I logged in again, only the Software Rasterizer was available according to glxinfo. I'll attach the dmesg log, and a dump of the i915_error_state file.

Ping--Is there any other info needed?
http://www.mediafire.com/?qm7nckc1da444rc Here's an apitrace file (with the bigger CompressedTexImage2DARB calls ripped out to cut down on size dramatically) that still reproduces the hang with mesa 5a7c3433 and kernel 3.2.0.
This is fixed by the last render target select patch on the mailing list. Will commit it shortly...
Fixed on master by: commit 172bb92db1a3c317867d9cfec6f15c09c37a0f6c Author: Kenneth Graunke <kenneth@whitecape.org> Date: Sat Feb 18 21:29:29 2012 -0800 i965: Only set Last Render Target Select on the last FB write. Fixes GPU hangs in OilRush, Trine, and Amnesia: The Dark Descent, which all use MRT (multiple render targets). NOTE: This is a candidate for release branches.
