Hi everyone, (please Cc) I am running 3.7-rc2 and got recently hit a few times (under rc1, too) by hanging drm i915 while doing large io operations. The efect in the dmesg: [13193.297751] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [13193.297758] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [13193.302728] [drm:init_ring_common] *ERROR* failed to set render ring head to zero ctl 00000000 head 85a05e3c tail 00000000 start 00003000 [13193.357584] [drm:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001 head 85a05e3c tail 00000000 start 00003000 [13194.861769] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [13194.861838] [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged! [13194.861840] [drm:i915_reset] *ERROR* Failed to reset chip. I captured the i915_error_state and uploaded it here: http://www.logic.at/people/preining/drm_i915_error_state.gz The hangs have been normally initiated on svn up in a very big repository, or git checkout on a very big repository or so. Other system is Debian/unstable. The above output and error state is from after a reboot without any suspends or other tricks inbetween, uptime 3.5h.

The dreadful sinking sensation in a long passageway encounter when both protagonists immediately realise they have plumped for the corriedoo (q.v.) much too early as they are still a good thirty yards apart. They were embarrassed by the pretence of corriecravie (q.v.) and decided to make use of the corriedoo because they felt silly. This was a mistake as corrievorrie (q.v.) will make them seem far sillier. --- Douglas Adams, The Meaning of Liff _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
