[22168.029016] [drm] GPU HANG: ecode 9:0:0x84dffff8, in Xorg [2693], reason: Engine(s) hung, action: reset
[22168.029022] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[22168.029025] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[22168.029029] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[22168.029033] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Assigning to Mesa product (please let me know if I am mistaken with this GPU Hang).

From this error dump, hung is happening in batch with active head at 0xff01593c, with  0x7b000005 as IPEHR

I set to "unspecified" version since this is 12.0.1 which is not available in the version picking list
Comment 3 Matt Turner 2016-11-04 00:21:25 UTC
Please test a new version of Mesa 13 and mark as REOPENED if you can reproduce and RESOLVED/* if you cannot reproduce.
Comment 4 Annie 2017-02-10 22:38:35 UTC
Dear Reporter,

This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested.

Thank you.
