    I'm not sure I can do this at all, and certainly, not this weekend. If
    anyone already has a serial console set up, the problem should not be
    difficult to reproduce in the following easy steps:

    1) On a fresh 6.0-BETAX, install the audio/timidity++ port and try

            gdb timidity

    2) Once in the debugger, run the program to play your favorite tune, such
    as on downloaded from:

            http://www.fortunecity.com/tinpan/vanishing/189/themes/PinkPanther.mid

            (gdb) r /tmp/PinkPanther.mid

    3) Interrupt the play by pressing Ctrl-C.
    4) Try exiting the debugger... *BOOM*.

    To save time, be sure to either unmount your filesystems or remount them
    read-only. Thanks!
