I would like to know some more information here.

1) Does this happens by just enabling the "CONFIG_XEN_PHYSDEV_ACCESS" in domU, without hiding any PCI device from Dom0 and without passing pci device to DomU.

2) If you are doing all these:
      a). hiding the pci's from dom0 by specifing the pci = [ x,y,z ] in the config file and the      physdev_dom0_hide option for xen-2.0.gz
      b). enabling CONFIG_XEN_PHYSDEV_ACCESS for the domU kernel
      c). including the correct drivers in the domU kernel
then, make sure that the pci device values are given in Hexadecimal numbers

Can you provide pci device values here.

In fact I just re-read your post and I don't have exactly the same problem. But your post answers mine :p Just disabled Physical Acess and it's working now. I will also need a pci access later for an externel encryption pci device, so I am curious to know about solution for your problem since I will for sure run into it.

It looks like we ran into the same problem, I posted a mail to the mailing list a few hours ago. I got same bug, whatever option I enabled or disabled.

Let's hope someone will be able to answer ;)
