Re: [Xen-users] pci passthrough toubles in debian xen 3.4.1

Ok, going through dmesg I can se that the usb stuff is loading before xen-pciback. This I would suspect to be the issue.

could I change this sequence in initramfs?

Would it be possible to solve this by using grub rather than initramf to hide the devices?
Not with xen-pciback built as a module, I don't think, since the
important thing would be the sequencing of the module load order, which
is independent of where the module parameters are stored.

I don't know if this gives me anything new, but then again black-listing ohci_hcd does not work. Maybe this is the reason?
That would be my guess. I know that initramfs tools handles usb drivers specially under some circumstances (for usb root, I suppose), which perhaps breaks blacklisting somehow. Ian.
