modprobe no such device error after remove/rescan

It may be a wrong place to ask this question, but still I could not find the answer anywhere. It seems that after removing the card and then rescanning it again i cannot load nvidia anymore. I get: modprobe: ERROR: could not insert 'nvidia': No such device The output of dmesg is: [ 103.648841] nvidia-nvlink: Nvlink Core is being initialized, major device number 234 [ 103.648845] NVRM: The NVIDIA GPU 0000:01:00.0 NVRM: (PCI ID: 10de:1c8c) installed in this system has NVRM: fallen off the bus and is not responding to commands. [ 103.652050] nvidia: probe of 0000:01:00.0 failed with error -1 [ 103.652060] NVRM: The NVIDIA probe routine failed for 1 device(s). [ 103.652061] NVRM: None of the NVIDIA devices were initialized. [ 103.652437] nvidia-nvlink: Unregistered the Nvlink Core, major device number 234

I made a dry-run of the script and experimented with executing commands manually. It seems everything working just fine, if only i do not run the remove command. More precisely, I can load the drivers, start xinit with nvidia working correctly, close the X server, unload the drivers and everything seem to be working. I checked that pci buses are correct, lsmod shows drivers load and unload completely. I also checked with lspci that card disappears correctly after remove and appears again after rescan. However, after remove/rescan procedure i can no longer load nvidia and get the aforementioned errors.

Did you by any chance know how to solve this problem?

Yeah even I'm seeing this error, no clue as to why this happens

Okay I did some fidgeting and ran these two commands nvidia-modprobe nvidia-persistenced And now I can load nvidia back again

Sorry, now I just get "modprobe: FATAL: module nvidia is in use." when trying to unload nvidia, even though nothing except nvidia-persistenced is running.

Yep kill that nvidia-persistenced it'll not let you unload nvidia, I was trying to find a fix but I'm not getting the time
