This CD should come along with a file called "System.map".

This basically means that either the kernel did do some bad things to
the hardware and was shot dead, or the hardware is broken.

My guess is that it's Linux' failure; for sure, it's not a computer type
detection problem.

Take the System.map from that CD and find lines in the form
"<some address> <function name>". In this file, look up the functions to
which the "pc" and "ra" addresses belong. (The file always contains a
function's start address, so most probably you won't have exact matches,
but you need to find the largest mentioned address being less or equal
the "pc" or "ra" address.)

After you've looked up those two, we can probably guess what's going
wrong here.

Look up the Program Counter and Return Address and let's see what we can
make out of that information :)
