This has nothing to do with interupts; as the error message *clearly*
states, the problem is I/O ports. If you can change the "PnP OS" option
in your BIOS setup, you should turn it "off". The problem is that your
BIOS isn't setting up the PCI device.

It's a CardBus bridge, so this won't work.

If you can't turn the "PnP OS" option off, you're stuck until we finish
PCI resource assignment in 5.x.
