[  291.561869] localhost.localdomain kernel: [drm] GPU HANG: ecode 6:0:0xc5ffffff, in gnome-shell [2149], reason: Hang on render ring, action: reset
[  291.561873] localhost.localdomain kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  291.561874] localhost.localdomain kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  291.561875] localhost.localdomain kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  291.561876] localhost.localdomain kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
