I have managed to "reduplicate" at least five times the
following scenario with a cisco as5250, with firmwrare
12.2 (11t) release firmware of cisco:

nmap -dinsane -p 1-65535 ip.of.as5350 This causes a
"hard" lockup, and the device must be powered off in
order to have functionality restored to it.

Mentioned to PSIRT at cisco, they didn't do anything.
