Public bug reported:
Binary package hint: yelp
I have dell studio 1737. Udev load CPU too much for several hours.
Starts suddenly and suddenly stops. Most frequently happenned after
return from suspend. Issuing udevadm control --stop-exec-queue helps,
but udev doesn't recognise any new devices connected to usb.
