My theory: Some driver is attempting outb() to a device which isn't on
a supported bus. ie outb is dereferencing a NULL bus_ops ptr.
The right way to find the culprit is to unwind the stack
by hand to find who called outb.
Seems removing the offending driver from the .config should solve
the problem for now. The right fix is to modify the driver so it
doesn't poke IO port space unless it's clear the device lives under
a suppported bus.
