I can reproduce this on my ivb, but it takes a few loops of ZZ_hangman. How reliably can you hit this? (In reply to comment #1) > I can reproduce this on my ivb, but it takes a few loops of ZZ_hangman. How > reliably can you hit this? Every time I run hangman will cause this error. I've noticed that disabling rc6 with i915.i915_enable_rc6=0 makes ZZ_hangman completely stable for me on both ivb&snb, even when I run it in a loop. Note that you need to have a sleep 10 in that loop, otherwise the kernel complains about the gpu hanging too fast and stops accepting batchbuffer commands. I usually do while tests/ZZ_hangman; do sleep 10; done that will stop as soon as the gpu died. Can you confirm that disabling rc6 makes gpu reset stable for you, too?

Yes, I disable rc6 , and the gpu reset turn to be stable.the dmesg shows: [ 302.188495] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung [ 302.188551] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 302.191248] [drm] Enabling RC6 states: RC6 off, RC6p off, RC6pp off I've created some patches to make the gpu reset more stable. Can you please test my reset-fail git branch from my personal git repo? http://cgit.freedesktop.org/~danvet/drm/log/?h=reset-fail Created attachment 63426 [details] running hangman with reset-fail's debug info (In reply to comment #5) > I've created some patches to make the gpu reset more stable. Can you please > test my reset-fail git branch from my personal git repo? > > http://cgit.freedesktop.org/~danvet/drm/log/?h=reset-fail I try reset-fail with its latest commit: Kernel: (reset-fail)aefaf55d4cbb279d5029fdaf428edd22a83f575f and attach the dmesg Looks like it works now with -fixes merged in. Can you confirm that the gpu works after running the hangman test (i.e. running gl apps doesn't crash it)? (In reply to comment #7) > Looks like it works now with -fixes merged in. Can you confirm that the gpu > works after running the hangman test (i.e. running gl apps doesn't crash it)? I run glxgears after hangman test, it can work well. Ok, patches are now all merged to -queued. Closing old verified. |
