Jul 25 11:14:41 cert kernel: [ 3449.035862] [drm] GPU HANG: ecode
9:0:0x85dffffb, in Xorg [5189], reason: Hang on render ring, action: reset
Jul 25 11:14:41 cert kernel: [ 3449.035863] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Jul 25 11:14:41 cert kernel: [ 3449.035864] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Jul 25 11:14:41 cert kernel: [ 3449.035865] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Jul 25 11:14:41 cert kernel: [ 3449.035866] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
Jul 25 11:14:41 cert kernel: [ 3449.035868] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Jul 25 11:14:41 cert kernel: [ 3449.035921] drm/i915: Resetting chip after gpu
hang
Jul 25 11:14:41 cert kernel: [ 3449.035998] [drm] RC6 on
Jul 25 11:14:41 cert kernel: [ 3449.047772] [drm] GuC firmware load skipped
/sys/class/drm/card0/error is empty, probably because I can only access it
after rebooting/logging in again.
I use xorg 1:7.7+19 from Debian Stretch.</pre>
