Ok, now we have a memory window created, which looks better, but its
addresses are wrong.

Thanks for this log. I need a bit of time to analyze this with the
PCI-to-PCI bridge specification, and I'll cook up a new patch,
hopefully tomorrow.

Thanks again a lot for taking the time to report this bug and test the
patches,

Thanks!
