I did, and it contains no details about your system configuration at all.

Perhaps, but it has been a module in at least the last 3-4 releases 
(since I started using it).

My point is that the chances are that the problem you are having should 
be fixable without changing the kernel build configuration.

If modprobing xen-pciback causes a hang, what parameters are you passing 
it? Do you have anything referring to xen-pciback in /etc/modprobe.d or 
on your kernel command line? Did you black list all the drivers 
controlling the physical devices you intend to pass through, and have 
you verified those devices are not loaded?
