Compositor [2296], reason: Ring hung, action: reset
Jan 23 20:11:31 hydra kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
Jan 23 20:11:31 hydra kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Jan 23 20:11:31 hydra kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
Jan 23 20:11:31 hydra kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
