This sounds very much like some module registered IO ports/memory and was
then unloaded without unregistering them.
It's a bit hard to guess which module it is, though. The oops says "[last
unloaded: parport]", so that's likely to be the area.
So I *suspect* this patch might be relevant. Bug apparently introduced in
f63fd7e299ee13da071ecfce2b90b58c5e1562b1 ("parport_pc: detection for
SuperIO IT87XX POST") by Petr Cvek.
