I was hoping to find the hardware somewhere to dig deeper into
this. But until I know more please apply the patch. There are
two possibilities that still exist, 1) it is true for all devices
on this motherboard (in which cases it should be a PCI quirk),
2) it is a driver bug. The test was going to be putting a skge
pci card in a slot on the MB.
