I meant "generic" in the sense that perhaps it's related to buffer manipulation
and not specific to Linux, not that it was commonplace! :)

You will need to redirect your console to /dev/tty10... then have another
terminal or shell monitor the output (could be as simple as minicom... with
history, hung off the machine over a null modem) I've done this plenty of
times... in fact... all of my headless boxes have the console directed to the
serial port.

Uh, right, that's what I want to do.
But _how_ do I do it? What commands do I type and where?

uh, no. A "kernel panic" is a "casters-up" dead-as-a-doorknob condition...
the kernel is not running... it has stopped.

True, the panic kills it, but it takes quite a while (minutes) to die. It's
generating recursive faults for quite a while, and it's still writing to the
screen of tty10 if I'm already viewing that (but kills the keyaboard, so I
can't change to that VT if I'm not already there). But there seems to be some
hope at least that it might still write to the serial port.
I don't want it to even try to write to the disk, however, since that might
just trash the entire filesystem. That's what I was trying to get at by
"reasonable". If it doesn't work, then it doesn't work, but it can't hurt to
try.
Or perhaps Linux has a kdb equivalent?
Thanks again,
Simon
