ok, your problem is that something is constantly adding and removing the nvidia module (and, doing other related device processing). That has nothing to do with this bug's problem, which is ONLY for udev looping due to rules in the bluez package's hid2hci rules file. I updated the bug subject to clarify that (scanning back through all the comments, I think most if not all of the discussion focuses on this specific package and rule).

You do seem to be having some other problem, which probably is with the nvidia-persistenced.service, provided by the nvidia-compute-utils-NNN package (with NNN being a number). Check:

$ dpkg -l | grep nvidia

to see the specific package name/version on your system. I don't really know what the problem is there, but you could try removing the package (if you don't need it), or searching for and/or opening a new bug for the problem.
