:My apologies for unwarranted assumptions.

:OK, I've compiled up with DDB and -g and I get the following
:(transcribed by hand, so mind the typos!):

:Asking DB for a panic at this point just hangs the system at the
:"syncing disks..." prompt. I assume that is the same problem.
:
:FWIW: All this time, the Alt-Fn still works, until I tried to Alt-Fn
:to the Xserver. Then it all hung.
:
:Anything else I can try?
Yah, do a 'ps' from DDB. If Alt-Fn still works the interrupts still
work which means it is probably a sleep/wait lockup of some sort. DDB's
ps will tell you what processes are waiting on, similar to what
'ps axl' from a shell prompt does.
