Public bug reported:
On a machine where nvidia-367 is installed, but the driver won't attach (due to
the nvidia card being older and requiring legacy drivers), systemd-udevd
repeatedly attempts to load it anyway, causing high CPU and memory usage. I
observed the systemd-udevd process at 98% CPU usage and 2.5G RSS reported by
top(1); restarting the service reduces resource usage momentarily, but it
appears to be climbing back up (I suspect the number of events is growing).
Workaround is of course installing the correct driver package, but udevd really
ought not behave like this if something fails to load.
Some journal entries for systemd-udevd.service:
