After 11 days of uptime, I typed 'fwcontrol -p' from a ssh session and  
my system rebooted.  This is all the information I could obtain.   
After reboot, fwcontrol did not cause another panic.  I do no have any  
swap nor did I get a chance to enter the debugger before the reboot.   
I'm currently in the process of updating to 188474 and will report  
back if this happens again.
