systemd-udevd keeps trying to run nvidia-modprobe indefinitely

Description:

systemd-udevd will now indefinitely try to run nvidia-modprobe when nvidia-modprobe exits with an error. I have tracked it down to this commit: 4fe55fc1

I am already binding a VFIO dummy driver on boot, as described here: https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Isolating_the_GPU

This causes nvidia-modprobe to always exit with exit code 1 and systemd-udevd will spawn a lot of worker processes, hogging down the system and actually causing noticeable lag. Downgrading nvidia-utils to version 545.29.06-1 is a workaround.

Additional info:

  • package version(s): 545.29.06-3
  • config and/or log files: systemd-udevd.log
  • link to upstream bug report, if any: -

Steps to reproduce:

Bind the VFIO dummy driver on boot and reboot. Maybe loading the nouveau driver will show the same behaviour, but I have not tested this.
