What I was told to attach by dmesg
[drm] GPU HANG: ecode 6:-1:0x00000000, reason: Kicking stuck semaphore on render ring, action: continue
[231430.174287] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[231430.174287] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[231430.174288] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[231430.174289] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[231430.174290] [drm] GPU crash dump saved to /sys/class/drm/card0/error

I saw this on another thread:
can you reproduce issue with "drm.debug=0xe" in your boot command line and then attached your dmesg.
So I'll do that too, but it's an "I don't know how to reproduce it but I know it'll happen again" type thing.
Semaphores are now disabled on gen6; use i915.semaphores=0 in the meantime.
