gpu crash dump
Hi,
DMesg gives me the following output:
[Di Jan 5 17:34:29 2016] [drm] GPU HANG: ecode 6:-1:0x00000000, reason:
Kicking stuck semaphore on render ring, action: continue
[Di Jan 5 17:34:29 2016] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[Di Jan 5 17:34:29 2016] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[Di Jan 5 17:34:29 2016] [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
[Di Jan 5 17:34:29 2016] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
