One thing to try in the future, before power cycling, is to plug a serial
cable into the console port and then unplug the ethernet. If this
"unlocks" the PM3, you are probably under a Denial Of Service attack
(DOS). It is nearly impossible to prevent these attacks, and they can
bring just about anything to its knees.
