Hmm... well, the 'davidw_debug' is supposed to crap out.  It's a
function that calls printk, which I have been told is not really
available at that point in the game.  I have noticed that I get a nice
'default catch' when it hits the printk, whereas, if I move the
function further down the list of things that happens, it apparently
isn't reached (or at least nothing is printed), as nothing crashes.

Maybe I should use a function that is guaranteed to crash?

Anyway, by moving this 'bomb' function around and rebooting way too
much, I narrowed down a region of code that I don't get the crash
after (meaning it hasn't reached my crash function or that it is
suddently ok to call it).  That's what I posted...

It's been quite time consuming, and not very elegant, but lacking
anything else, it's all I have really (supposedly, someone is getting
me a null modem cable tommorow so that I can try and connect to the
serial port).

Thanks,
