With todays master I still get GPU hangs...

[Mo Jan 29 09:18:59 2018] [drm] GPU HANG: ecode 7:0:0x85dffed2, in glretrace
[32025], reason: Hang on render ring, action: reset
[Mo Jan 29 09:18:59 2018] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[Mo Jan 29 09:18:59 2018] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[Mo Jan 29 09:18:59 2018] [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
[Mo Jan 29 09:18:59 2018] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
[Mo Jan 29 09:18:59 2018] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
