I suspect it is this bug:=20
http://thread.gmane.org/gmane.linux.hotplug.devel/11001

Look into /etc/udev/rules.d/70-persistent-net.rules, and=20
into /dev/.udev/tmp-rules--70-persistent-net.rules if there are rules that =

set the same name for two different cards (mac addresses).
The tmp-location is used as long as / is read-only at udev startup time.

Easiest is to delete both files and reboot / or edit the set names for=20
net-devices to be unique. Then the error should be gone.
If not you found another bug.

This is OK, it's the new name-encoding.
