Kernel: 3.15.0-rc6+
Noticed following in the kernel log, but no idea what caused this:
[snip]
[27311.226010] [drm] GPU HANG: ecode -1:0x00000000, reason: Command parser
error, iir 0x00008000, action: continue
[27311.226010] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[27311.226010] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[27311.226010] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[27311.226010] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
