Same problem here.
I'm using gentoo with kernel 3.5.3 (gentoo-sources) and XEN 4.1.2 as dom0.
DomU is also gentoo with the same kernel version.
When I assign more than 4G memory to this domU, the memory for the
passed-through Intel-gigabit-nic cannot be allocated and the
initialization of the device fails.
With 3968M memory assigned everything works fine.
Assigning 8GB RAM to domU works without any problems, when I use the
old kernel-version 2.6.34 (xen-sources) in domU.
Regards
Daniel
