Hello mwa,
The bad news is I also reproduced this issue after I downloaded the guc
firmware and enabled it in i915.

The error log as below:
[  252.697245] [drm] GPU HANG: ecode 9:0:0xfffffffe, in nexuiz-linux-x8 [2970],
reason: Hang on render ring, action: reset
[  252.697247] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  252.697248] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  252.697249] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  252.697250] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
