Ivan Kokshaysky 73a74ed3a6 PCI: i386: fixup for Siemens Nixdorf AG FSC Multiprocessor Interrupt Controllers
Wolfgang gets:

 PCI: Cannot allocate resource region 0 of device 0000:00:04.0
 PCI: Error while updating region 0000:00:04.0/0 (a8008000 != fec08000)

Note that the BAR seems to have high address bits hardwired to fec00000.
And device 0000:00:04.0 is

 00:04.0 System peripheral: Siemens Nixdorf AG FSC Multiprocessor Interrupt Controller (rev 02)

I'd guess that when we try to reassign this resource, PCI interrupts might
just stop working. This could explain SCSI timeouts and other weird things.
