Is this still a problem for you? I've run: while true; do mesagl /usr/lib/xscreensaver/lattice&; sleep 1; killall lattice; done and same for hyperspace, for several minutes each on 965GM (T61) and G45, with no troubles. OK, I've pushed a commit series that should fix GPU hangs with DRI2 in use. The symptoms in the GPU dumps are unreliable, as sometimes the corruption would occur in a state buffer not dumped in the intel_gpu_dump output, but I've definitely seen the symptoms of this in a number of the reports. Please retest with this set of changes, and reopen if the problem continues. (in this case, your dump shows a depth buffer that would have drawn around 4 pages outside of its buffer) xf86-video-intel: commit e8f0763d405a8152c74c28792c52fe12c1d41dd5 Author: Eric Anholt <eric@anholt.net> Date: Fri Aug 7 18:24:44 2009 -0700 Fix math in the tiling alignment fix. commit 222b52ef16895823fbf3a0fc0be4eb23b930ed1b Author: Eric Anholt <eric@anholt.net> Date: Fri Aug 7 18:05:29 2009 -0700 Align tiled pixmap height so we don't address beyond the end of our buffers. Mesa: commit ceb8afcca5b0a52b005a782ea54b301beaee1a15 Author: Eric Anholt <eric@anholt.net> Date: Fri Aug 7 18:09:31 2009 -0700 intel: Align region height as required for tiled regions. Otherwise, we would address beyond the end of our buffers. Fixes reliable GPU segfault with texture_tiling=true and oglconform shadow.c. Bug #22406. Cool, I'll take a look at it. Thanks! - Ben |
