I've been having inexplicable crashes for a while and finally got around
to getting a debug kernel and checking out what's going on, so here
goes (apologies for the ^M's and all, I scripted a gdb session and that's 
what I got...):

panic: bdwrite: buffer is not busy
panic messages:

I've caught a few of these by hand while working in the console before,
but thought they'd been resolved until now.
