Ran the update on my pro, no issues. However I boot with nothing plugged in and have disabled the udev automount rules. Once booted up i then plug in my printer and HDD (plug won't boot if HDD plugged in at boot/reads HDD before USB(rootfs) drive) and no udevd power load.
Without udev-compat
Dunno what to tell ya devr. Maybe check your configuration or your fstab?
EDIT: just ran udev-compat, udevd now runs ~7%. I don't remember what the norm was prior to these issues but this beats 100%. If you reboot, check daemons.log to see if continuous printing of udev errors occur (or if syslog-ng is running hard it's probably due to udev errors as WHSE pointed out on the Pro forums).
My pro runs normal now, connectable and avg cpu load of 8.9% will all apps running.
