Hey Josh.

Try to get trace output, which you will only be able to type in.

If you have a big enough swap space, you can try sync, but I'm not
sure if it will save a panic over NFS? Actually, I'm not sure if will
save a panic to a regular file which is how some of us had it set up.
I seem to remember something related to not being able to save a panic
on the dreamcast.

I haven't tried mine in a while now, I should try it. I'm trying to
build 3.0-release right now for a few boxes, maybe I'll build it for
Dreamcast as well...
