Thread-topic: [Xen-ia64-devel] DomU not booting?
Looks like some dirty pages allocated for pmd or pte page... lookup_domain_mpa 
failed first, however later map_new_domain_page found pte present after 
allocating new pmd/pte pages. Could you make a check whether the allocated page 
table pages is zero-ed?

BTW, just confirmed scrub_heap_pages not invoked when running on ski, which is 
from Dan who encountered issue long time ago. If you're running on Ski, that's 
one possible reason.
