Hi Yamata,

   I tried alloc_domheap_pages(NULL, 0, 0) in pgtable_quicklist_alloc().
I don't have physical access to the system right now to remove ram,
instead I booted with max_addr=1G on the xen half of the append line.
With that I hit a BUG in ia64_handle_reflection().  Here's the log.
Thanks,

        Alex
