xorg.log from GPU HANG with modeset, Mesa 13.0.3 and Linux v4.10-rc4

This is the log with the actual GPU HANG event, as you can see by matching up
the Modeline log lines with the timing of the GPU resets:


[19308.656674] [drm] GPU HANG: ecode 9:0:0x84dfbffc, in Xorg [1171], reason:
Hang on render ring, action: reset
[19308.656769] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[19308.656770] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[19308.656771] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[19308.656772] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
