I got a crash after a few minutes of running 3.8.0-rc2, was able to switch to a vt and look at dmesg: [ 490.962545] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [ 490.963019] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 492.961446] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [ 492.965613] [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged! [ 492.965621] [drm:i915_reset] *ERROR* Failed to reset chip. Previously I was on 3.6.10-2.fc17.x86_64, which didn't have any such problem. dmesg, config, and i915_error_state available from: http://fieldses.org/~bfields/3.8-hang/ --b. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
