first, do a 'trace' in the debugger and report the stack here.  perhaps
someone will be able to help you figure out what went wrong in the first
place.  what kernel are you running, btw?

in general, if the kernel panic's, something is hosed and you need to
reboot to fix things up.  i think you can type 'cont' to continue from the
debugger, but you're probably not going to get anywhere.  you can compile
a kernel without the debugger and the machine will reboot spontaneously if
you want to minimize downtime.

later.
