problems dropping to single user from multi in recent -current?

I've updated several boxes over the last few days -- these are all
serial console units; and everytime I issue 'shutdown now' to 
drop to single user, it hangs at the pathname prompt.  Is anyone 
else seeing this?

example:
# shutdown now
Shutdown NOW!
shutdown: [pid 1021]
