panic during install

[Matthew Dillon]

:While testing the installer, I got a panic in a seemingly random place. 
:I don't have a dumpdev or a debug kernel on the installer image, so I
:can't get a dump with symbols (until I can reproduce it on the installed
:system, if I can,) but here's what I do get (minus addresses):

    That's filesystem corruption on /mnt.  What did you have mounted 
    there?  Something old?  Something new?
