Dear list,
I had to do a bios update due to some bugs in the Mgmt Engine.
After this I had to re-enable the VT and VT-d made a power cycle, but
since then VT-d is not enabled via hypervisor.

Aditionally "xm pci-list-assignable-devices" brings no output.
I even tried xen-unstable, but there is still the same :-((
Please, can anyone help me, or give me a hint, what else I can do to
get VTD back working? It worked until the bios update. Details follow:
