A bogus GUID.

Something on the host is to be shut down, but that does not work.

The last value is bogus. IIRC it cannot be more than 4096 with
IEEE 1394a-2000.

Not actually. Obviously, the ohci driver has a really hard time
to do anything useful with that (onboard?) controller. I don't
know, maybe some registers cannot be read...

It could be related to PCI resource management rather than to
ohci1394.
