I haven't had as much time to investigate this as I wished, but I did
manage to attach a serial console and capture boot -v.
So how do I track the pc listed in the trap message down to a line of
code?
I've taken the fxp card back out and the box is up and remotely available
for further investigation... What do I do next?
