So, I can't get my via82cxxx module to load and I can't build via82cxxx
into the kernel because it causes a kernel panic. I am attaching the
ksymoops output and a snippet of the section of the dissassemble of the
function with gdb. I am still going to play with this more to see if I
can track it down but if someone wants to lend a hand, it would be most
helpful as I am not the advanced kernel coders that most everyone else
on this list is.
