Well, acx100_pci seems to be buggy.

It's probe function is at address 0xd0823000 which is where your OOPS
is happening. I suspect you'll find the acx100 pci probe function is
marked with __init. That's a bug - it must not be.

Similarly, the PCI ID table must not be marked with __devinitdata nor
__initdata.

(I can't reach acx100.sourceforge.net currently.)
