The note in /sys/pci/ncr.c points this towards a PCI bus problem. The first line comes from a caching test that verifies that the NCR's regisers are not being cached by writing 0xffffffff to a read-only register. If it reads back 0xffffffff then your PCI chipset is caching the result and not actually writing it to the chip. Check your BIOS settings and see if you can disable PCI write caching.
