I just noticed I can no longer use bluetooth with the 4.14.15 kernel. This
laptop has a shared bluetooth and WiFi mini card, which has never worked
properly (see attached hardware details).
Although MWindows has no problem, in Linux I have to disable WiFi when I need
to use bluetooth! O_o
Anyway, I now discovered that bluetooth won't work and /lib/systemd/systemd-
udevd --daemon is pegged at 100% of CPU time. Switching off the mini-card
using a keyboard button does not stop udevd from running hot. It just drops
from 100% to 45% until I kill the process manually.
udevadm monitor shows:

non stop. Syslog does not show anything unusual.
Has anyone noticed something similar? How do I troubleshoot this?
