system won't reboot

[Dana Holland]

I'm having another issue with the same system.  When we issue a 
"shutdown -Fr now", the system won't reboot on it's own - we have to 
physically turn off the server and turn it back on.  On the screen it 
hangs at the line "Restarting the system".  I've tried going through the 
various logs to find a clue, but the only thing unusual I'm seeing is 
this, which is found in boot.log.

Can anyone point me in the right direction to find our problem?
