Re: [Xen-users] Debian Squeeze - XEN and PCI Passthrough

[Francisco Javier Funes Nieto <esencia@xxxxxxxxx>]

Hi,

The same ISDN Card in Debian Lenny (with 2.6.22-xen-amd64)  and Xen
3.4.3 works well.

module          /boot/vmlinuz-2.6.26-2-xen-amd64 root=/dev/sda1 ro
console=tty0 pciback.hide=(02:04.0)(04:00.0) pciback.permissive
pci=nomsi


Try adding pci=nomsi to boot parameters in grub.cfg

More info about the dom0 hardware?
