journalctl output for last boot to crash

I'm experiencing a random, but consistent hard-free (cannot switch virtual
terminals) running an nVidia card with three monitors under Fedora 25. Recent
kernel and driver updates have seemed to make this freeze much more frequent
(5-6 times in two work days).

Journalctl -b -1 output is attached. Most relevant lines are:

kernel: nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
kernel: nouveau 0000:01:00.0: fifo: gr engine fault on channel 12,

A possibly related bug is #96562, but it is old and hasn't received any
attention, so I'm opening a new one.
