Excellent! That's exactly what I want. Thanks for the tip.

I've finally managed to get another g4 (I'm at a different office)
to boot a debug kernel. Now, when this machine panics, I see:
<stack trace>
Waiting for remote debugger connection.
Options..... Type
------------ ----
continue.... 'c'
reboot...... 'r'
enter kdb... 'k'
However, I cannot seem to type anything on the "graphics" console.
I was logged into the console at the time of the crash in text mode,
via entering >console as the username; eg no windowing was running.
Do I need to be running with a serial console? Or doing anything else
differently? Or is it looking to talk kdb over the network?
FWIW, the behaviour is the same (minus kdb) with the 1.4 kernel which
ships with OS-X 10.1
BTW, does devfs_remove() work? I don't see any other code using it,
and its where my current panic is happening (on the 5th call to it,
out of 64 device nodes).
Cheers,
