Hi @all,
I tried to give a PCI device to a domU with
module /boot/vmlinuz-3.2.0-0.bpo.2-amd64 ... xen-pciback.hide=(02:01.0)
vai /boot/grub/grub.cfg
The startup of the domU shows this error:
Loading DAHDI hardware modules:

Running dahdi_cfg: .
also a lspci shows different to to dom0:

Thats the output without pciback:

May somebody have a hint, what to look for?

I could not get the first device to pass through until I added another PCI device before it. Very strange.xen bug maybe? James
