I updated my sources to the linuxppc_2_4 and the benh
kernel. The linuxppc_2_4 kernel will now not compile
so I used the 2.4.21-ben2 kernel. When I try to insert
the aic7xxx module (all compiled with clean build) I
get a bus error. If I try to insmod again I get "
a module buy that name alread exists". If I try to rmmod
I get "device or resource busy".
This is the oops:
Machine check in kernel mode.

I have mixed feeling about posting this because it looks like
something went seriously wrong. Maybe it's someting useful
to you. I am going to wipe the kernel modules directory and try again.
