/sys/class/drm/card0/error on 4.10.9-200.fc25.x86_64

Just hit the bug again. This time on v4.10.9 and it managed to recover(killed
my desktop session though but at least, no need to hard reset):

[ 2608.203791] [drm] GPU HANG: ecode 6:0:0x85fffff8, in Xorg [926], reason:
Hang on render ring, action: reset
[ 2608.213449] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2608.222579] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2608.231352] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2608.240900] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 2608.249759] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2608.256075] drm/i915: Resetting chip after gpu hang
[ 2619.190601] drm/i915: Resetting chip after gpu hang

Since it recovered, I can copy the said error file and here it is.
