--- Comment #2 from Aaron Lu <aaron.lu at intel.com> ---
Not sure if this is the same bug, the machine today already hang twice and I
saw the following message in serial log:

Fedora 25 (Workstation Edition)
Kernel 4.10.10-200.fc25.x86_64 on an x86_64 (ttyS0)

aaronlu login: [ 1674.330699] [drm] GPU HANG: ecode 6:0:0x85fffff8, in Xorg
[926], reason: Hang on render ring, action: reset
[ 1674.340346] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 1674.349471] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1674.358250] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1674.367804] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 1674.376668] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 1674.383004] drm/i915: Resetting chip after gpu hang

It's different than previous in that the system can not recover now and I have
to hard reset. The problem seems to appear quite often/easily from v4.10.9+
kernels shipped with Fedora 25.

Shall I file a new bug for it?
