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 dmesg as [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+0x20/0x20Clearly the amdgpu module crashed. I would like to restart it, so I tried sudo modprobe -r amdgpumodprobe: FATAL: Module amdgpu is in use.And when I try to find out who is using amdgpu I get lsmod | grep amdgpuamdgpu               2129920  7amdttm                102400  1 amdgpuamdkcl                 32768  1 amdgpui2c_algo_bit           16384  1 amdgpudrm_kms_helper        155648  1 amdgpudrm                   364544  10 drm_kms_helper,amdgpu,amdkcl,amdttmBasically there is 7 things using the module and I have no idea how to find them and remove the amdgpu module.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?
