My video card crashes from time to time. It's quite annoying but I live with it -- usually I just restart the graphics with
sudo systemctl restart lightdm.service, or if needed reboot the whole system.
In this particular instance the
systemctl call hangs, and I don't want to reboot since I have a long-running job on the machine.
The crash is logged in
[944520.212254] Call Trace: [944520.212256] [<ffffffff818384d5>] schedule+0x35/0x80 [944520.212257] [<ffffffff8183b625>] schedule_timeout+0x1b5/0x270 [944520.212280] [<ffffffffc0235244>] ? dce_v6_0_program_watermarks+0x514/0x720 [amdgpu] [944520.212282] [<ffffffffc0196d2c>] kcl_fence_default_wait+0x1cc/0x260 [amdkcl] [944520.212287] [<ffffffff815b4f50>] ? fence_free+0x20/0x20
amdgpu module crashed. I would like to restart it, so I tried
sudo modprobe -r amdgpu modprobe: FATAL: Module amdgpu is in use.
And when I try to find out who is using
amdgpu I get
lsmod | grep amdgpu amdgpu 2129920 7 amdttm 102400 1 amdgpu amdkcl 32768 1 amdgpu i2c_algo_bit 16384 1 amdgpu drm_kms_helper 155648 1 amdgpu drm 364544 10 drm_kms_helper,amdgpu,amdkcl,amdttm
Basically there is 7 "things" using the module and I have no idea how to find them and remove the
Question: Is there any reasonable way to reload the module, without rebooting the system? Or is there a better way to get my video back?
