[ 1244.000195] [drm] stuck on render ring
[ 1244.005991] [drm] GPU HANG: ecode 3:0:0x7f7fffc1, in Xorg [778], reason: Ring hung, action: reset
[ 1244.005999] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 1244.006003] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 1244.006007] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 1244.006010] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
