Created attachment 54288 [details] i915_error_state from debugfs after the hang With the latest xf86-video-intel from git and SNA enabled, running gtkperf causes my GPU to hang. Xorg.log and dmesg show nothing particularly interesting apart from the fact that the GPU is hung.
commit b5a6bc9e33a2797c926969e1f98b4a9a796248c5 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Dec 10 13:14:45 2011 +0000 sna/gen[23]: Fixup render targets with pitches below hw minimum gen2/3 have a restriction that the 3D pipeline cannot render to a pixmap with a pitch less than 8/16 respectively. Rather than mandating all pixmaps to be created with a stride greater than 16, fixup the bo for the rare occasions when it is necessary.
