My first bisect. Now I understand why you didn't have the time. 13
hours! Unfortunately, I'm not sure this is especially helpful.
I'm suspicious of the code for the pci core on the 500gp. The same
minipci card works w/ the b43 driver in my pc, b43 crashes on the 500gp.
I'm not sure I believe the traceback. Plus gcc's inlining all
subroutines only called once makes things really obscure.
I'll keep looking.
