I am having the following panic, with a -CURRENT system as fo CTM
cvs-cur.5868. I *think* the panic was induced by running mpg123 with a not
an mp3 file. I've had two (maybe three, something happened to the box over
night.) of these panics, but hte first was with no dump device configured.
I suspect I can reproduce it, since this one I did.
