May be a kernel compile option? It would be great if you can send me the .config file that you used to compile it, just to check the options.

Can you try out a few things, like booting off the 'avi' branch in
userspace and / or the 'kvm' branch of the kernel tree? Just to rule out
the bugs in the device assignment code.
