Hi,

I have cloned the latest xen 3,4 testing tree, changeset 19696:
        22ef8e900a6d (i386: fix handling of Xen entries in final L2 page
table), and i have installed it on a Lenovo T500 machine, with VT-d
enabled.

When i rebooted the machine, and try to boot xen with 'iommu=1' it
hangs during boot.  If i try to boot it with 'iommu=0', it boots ok.

These are the last lines of the UART output:
