It looks like its encountering a pfn (page number) that's greater than
the total number of pages given to the domain. 

Aaah, 36GB memory.  What happens if you configure
CONFIG_XEN_MAX_DOMAIN_MEMORY larger to match, or set dom0_mem to less
than 32GB?

(It shouldn't crash regardless, but it will confirm the diagnosis.)
