Comment # 46
on bug 93629
from Franco Forza
I've tested the 'NvGrUseFw=1' kernel cmdline argument (as stated in old comments from 2016 above) but it doesn't help anymore (the 4 requested fw files by nouveau during early boot were served properly and the errors about missing 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. Arch Linux 4.19.4 xf86-video-nouveau 1.0.15 modesetting mesa 18.2.6 xorg-server 1.20.3 Nvidia GTX770 (NVE4/GK104/Kepler)
