DDB use for boot process tracing

[David Riley <fraveydank%gmail.com@localhost>]

This will probably seem like a silly question to many of you, but I'm having 
some difficulty.  I'm trying to trace where the kernel is hanging on LCIII 
boot, and whenever I break with either Cmd-Power or a serial console break, the 
stack trace is not particularly useful (since it only traces back to the 
interrupt).  What do I need to do to trace back and see where I'm at in the 
kernel boot?

I'd just do a combination of next/until/etc, but after about a second of idle, 
some timer in the machine causes a panic and I have to reboot.  I suppose I 
could trace the stack back manually if I have to.
