Hi there,

On   6 Jun, this message from Andreas Tobler echoed through cyberspace:

See below; I've spotted one thing that probably breaks.

Yes, but it is not needed, I think.

This must be the conflicting resource, but it gets an equally-wrong new
address :-(( In fact, the PCI resource code still misses a patch to make
the correct resources available to the resource allocation code (so that
IO regions can be taken out of the IO region of the correct PCI bus..)

I'm still working on that part ;-)

So if the SCSI driver actually uses the IO region, it will most
certainly not work....
