Commen= t # 46 on bug 93629<= /a> from Franco Forza 
I've tested the 'NvGrUseFw=3D1' kernel cmdline argument (as st=
ated in old
comments from 2016 above) but it doesn't help anymore (the 4 requested fw f=
iles
by nouveau during early boot were served properly and the errors about miss=
ing
firmware files vanished as well).

The system freezes maybe once per week. Mostly hard crash with two keyboard
leds blinking and hard reset after some time. Sometimes the kernel survives=
 and
dmesg can be read out. It shows this:
[ 7896.354441] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[ 7896.354452] nouveau 0000:01:00.0: fifo: runlist 0: scheduled for recovery
[ 7896.354458] nouveau 0000:01:00.0: fifo: channel 2: killed
[ 7896.354464] nouveau 0000:01:00.0: fifo: engine 0: scheduled for recovery
[ 7896.354879] nouveau 0000:01:00.0: systemd-logind[473]: channel 2 killed!

If there's something we can do to help debug this let me know.
