--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
That kernel OOPS should be fixed in v4.13 (it's just warning that the state of
the request changed halfway through the reset request), with any luck it will
mark the driver as wedged as userspace managed to clobber everything in the
first few megabytes of the GTT.
