So you're saying that any recent Xen with any kernel is failing on
fairly recent hardware. Have you tried playing with the iommu boot
command line options?
Can you post a complete log of Xen's console output (both hypervisor and
kernel console)?
What is the hardware platform? Am I right in guessing that you're
seeing this on two distinct machines?
Thanks,
J
