Jan 26 15:06:57 gray-box-u kernel: [190454.804072] [drm] GPU crash dump saved to /sys/class/drm/card0/error
Jan 26 15:06:57 gray-box-u kernel: [190454.804075] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Jan 26 15:06:57 gray-box-u kernel: [190454.804077] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Jan 26 15:06:57 gray-box-u kernel: [190454.804080] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Jan 26 15:06:57 gray-box-u kernel: [190454.804083] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
