We had a thread before about usersapce loading the module multiple times on failure: https://lore.kernel.org/linux-edac/20190822005020.GA403@angband.pl/
I tried to look into it a bit, but I didn't get very far.
So is the behavior you see only happening with the new patchset applied? That may be a clue that we can fix this in the module.
