How to find the cause of a hang

Hi all,
I'm currently experiencing frequent (about once per week) hangs of a
server that is about 1500 kilometers away from me. I have a serial
cable on the box, and using minicom on the neighbor box I am now in the
kernel debugger - but I'm at a complete loss as to what to do to figure
out what is, in fact, wrong.
Calling panic or boot doesn't work - it just stops at "syncing
disks..." and never actually reboots. I suspect something fishy going
on with disk I/O, but I can't be certain of that.
The box responds to ping - until I call panic or boot - but no other
services are working.
What can I do? I'm now at the db> prompt ... Help :)
