[So Apr 26 10:07:53 2015] [drm] GPU HANG: ecode 8:0:0xfffffffe, in systemd-logind [925], reason: Ring hung, action: reset
[So Apr 26 10:07:53 2015] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[So Apr 26 10:07:53 2015] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[So Apr 26 10:07:53 2015] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[So Apr 26 10:07:53 2015] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
