    Thanks,

     Looks like that did some good (I have my console back now), but when i
    either "boot -g" or break into ddb and give it a "gdb" command, then try
    and connect gdb to it on the other serial port, gdb seems to not be able
    to connect to it (and I consequently have to power cycle the machine to
    un-hang it). What I get from gdb is the following:

    bash-2.05b$ sudo gdb -k kernel.debug
