same problem here. System freezes completely(except, I can move mouse pointer. Just move, no click) and after restart buch of "nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]" in syslog. ubuntu 16.04, 4.4.0-78-generic #99-Ubuntu SMP, Lenovo P50.
I cannot switch to nvidia-XXX driver as it is unusable in multiple monitors configuration.
