Another datapoint: just now a machine hangs just after printing the
line "Adding interface aliases" (haven't defined any) with its network
acivity led on the switch blinking like mad. After unplugging and
re-plugging the cable from the switch it starts to respond to pings
again, and booting continues.....

should I manually configure media types?, and could incorrect
autoselection of media type be related to the loopback failure?

any clues?
