Title:
[witherspoon] removing module nouveau causes cpu hard lockup
Status in The Ubuntu-power-systems project:
Triaged
Status in linux package in Ubuntu:
Incomplete
Bug description:
Installed 18.04 and upgraded kernel to linux-image-generic-hwe-18.04
(4.18.0-13-generic #14~18.04.1-Ubuntu SMP Thu Dec 6 14:03:47). Copied
gv100 firmware to /lib/firmware/nvidia, removed and reloaded nouveau
(modprobe -r and modprobe). Tried to remove nouveau again using
modprobe -r and I see the trace below. After a while the modprobe -r
command completed the module was removed successfully.
