This looks vagualy familiar. 

(XEN) mm.c:860:d0 Error getting mfn 80000 (pfn 5555555555555555) from L1 entry 8000000080000473 for l1e_owner=0, pg_owner=32753^M

If I remember right there was a similar issue where the DSDT had instructions to
poke at the IOAPIC or the northbridge. If you can perhaps follow (under baremetal?)
what is under MFN/PFN 80000 it might help.

Or maybe the kernel just failed to setup an ioremap.
