Created attachment 53271 [details] dmesg log from GPU lockup I'm not sure whether this is a new problem or just a particularly bad side effect of bug #41698, but WoW has now begun locking up after just a few moments of gameplay. I'm sure it wasn't as bad as this yesterday though. The latest commit in git is: commit dceb202297b39220fbbcb41267077fb3ff8d137a Author: Kenneth Graunke <kenneth@whitecape.org> Date: Mon Nov 7 12:07:44 2011 -0800 i965: Fix Sandybridge regression introduced by workaround-free math. And I'm fairly sure it was working yesterday with: commit 2318443ebd6bf9727676b530a3b057dcf13a3ca6 Author: Dave Airlie <airlied@redhat.com> Date: Sun Nov 6 19:38:50 2011 +0000 gl3.txt: update for ARB_texture_storage. There is something seriously wrong with r300g.
Could you please bisect?
(In reply to comment #1) > Could you please bisect? Haven't we already played the bisection game, though? I proved that commit: 363ff844753c46ac9c13866627e096b091ea81f8 is the first bad commit commit 363ff844753c46ac9c13866627e096b091ea81f8 Author: Marek Olšák <maraeo@gmail.com> Date: Tue Sep 27 01:10:20 2011 +0200 winsys/radeon: move GEM domains out of the drivers into winsys was bad ages ago, and have already mentioned getting a GPU lockup with it applied. Any new bisection must therefore include this "known bad" commit.
(In reply to comment #1) > Could you please bisect? The problem does not occur between dceb202297b39220fbbcb41267077fb3ff8d137a and 2318443ebd6bf9727676b530a3b057dcf13a3ca6, so I can only assume that these two GPU lockups were due to an intermittent bug that was already present. FWIW, there seems to be a small drop in FPS between Mesa 7.11 and Mesa git. 7.11 (strictly speaking, it's mesa-dri-drivers-7.11-1.fc15.i686) is giving me 10-11 fps in situations where git is currently giving me 7-8 fps. Possibly the lockup requires a certain level of graphical "business" which just isn't present at 12:30 AM.
Created attachment 53788 [details] Two GPU resets while playing WoW These two GPU resets happened in quick succession, although the kernel managed to recover each time. (Small comfort, I suppose). The kernel is 3.1.2, with Mesa HEAD at: commit 034e63b9f8ee23cfac769b1a2c431bdd2307a6c4 Author: Marek Olšák <maraeo@gmail.com> Date: Tue Nov 22 20:48:23 2011 +0100 r600g: handle all remaining CAPs This does not bode well for RV350 support with Mesa 7.12.
This hasn't happened for a long time.
