dmesg showing error

Intermittently (a few times a day), my display will completely freeze and
doesn't recover. Although the kernel doesn't hang and I can ssh in, I can't
chvt to a non-graphical VT.

Whenever this occurs, I see a message like this in dmesg:

[12535.260195] nouveau 0000:01:00.0: gr: TRAP ch 6 [007f778000 Xwayland[854=
]]
[12535.260211] nouveau 0000:01:00.0: gr: GPC0/TPC1/MP trap: global 00000000=
 []
warp 3d0001 [STACK_ERROR]
[12539.595312] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[12539.595318] nouveau 0000:01:00.0: fifo: gr engine fault on channel 5,
recovering...

Despite the "recovering..." message it never actually recovers an=
d only a
reboot solves the problem.

I'm using GNOME on Wayland, and I'm typically running gnome-terminal, Firef=
ox,
and/or Chromium. So far I haven't identified any specific action that trigg=
ers
this failure.

My computer is a mid-2014 Macbook Pro with a GeForce 750M (GK107). I'm runn=
ing
nouveau with "nouveau.nofbaccel=3D1". I've tried adding
"nouveau.config=3DNvGrUseFW=3D1" but it complains about not findi=
ng
/lib/firmware/nvidia/gk107/fecs_inst.bin. Is there an external firmware blob
available for this card?

I recently updated my kernel and several relevant packages, and have seen no
difference in behavior. I'm running linux 4.9.0, and the latest version of =
mesa
from git (36b5f1d200).

See my attached dmesg output. Is there any debug flag I can enable to shed =
more
light on the situation?

Thanks!
Tony
