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! -mi
