Sep 29 19:14:01 localhost kernel: [27470.108470] [drm] GPU HANG: ecode
7:0:0x85dffff8, in chromium-browse [3894], reason: Ring hung, action: reset
Sep 29 19:14:01 localhost kernel: [27470.108473] [drm] GPU hangs can indicate a
bug anywhere in the entire gfx stack, including userspace.
Sep 29 19:14:01 localhost kernel: [27470.108474] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Sep 29 19:14:01 localhost kernel: [27470.108476] [drm] drm/i915 developers can
then reassign to the right component if it's not a kernel issue.
Sep 29 19:14:01 localhost kernel: [27470.108477] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
Sep 29 19:14:01 localhost kernel: [27470.108479] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
