Haven't tested using 1394 or serial. Interestingly I was at console session #2, pressed ctrl+alt+esc but I needed to switch to session #1 to actually see the debugger prompt. Input goes to the debugger even while not seeing it's prompt. That reminds me of the old debugger problem when using X and experiencing a kernel panic. Volker
