According to the boot -v messages the I/O range map is getting attached to
the wrong function on that chip:
found-> vendor=0x8086, dev=0x25a3, revid=0x02
bus=0, slot=31, func=2
class=01-01-8a, hdrtype=0x00, mfdev=0
cmdreg=0x0005, statreg=0x02a8, cachelnsz=0 (dwords)
lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns)
intpin=a, irq=255
map[20]: type 4, range 32, base 000008c0, size 5, enabled
but it should be on this:
ichsmb0: <Intel 6300ESB (ICH) SMBus controller> port 0x8c0-0x8df irq 17 at
device 31.3 on pci0
I'll poke at this a bit, but you should check for a BIOS update.
