[Bug 1759836] Re: systemd-udevd consumes 100% of CPU

[Svip]

I am having a similar problem after upgrading to 18.04 on a Dell
Precision M4600, with the following specs:

- Intel Core i7 2640M
- NVidia Quadro 2000M

I have disabled Bluetooth entirely, because I don't need it.  But the
NVidia loading/unloading (add/remove) in udev keeps persisting.  I can
disable this by removing the nvidia-rules (71-nvidia-rules) from the
rules.d-directory, but that also disables the module entirely, and I
need the nvidia module, I just wish it would not unload.

This issue seems to be about Bluetooth, although plenty of mentions of
NVidia, should I create a separate one for the nvidia driver issue?
