Yes, it is the same crash. Going back to the dprintf command,
                DPRINTF("************** pfn=%lx type=%lx gotcs=%08lx "
                        "actualcs=%08lx\n", pfn, pagebuf->pfn_types[pfn],
                        csum_page(region_base + i * PAGE_SIZE),
                        csum_page(buf));
what does pagebuf->pfn_types[pfn] actually mean and how does it relate to 
the type= it matches. I suspect it should be something else, eg. 
pfn_type[pfn] which would give the page type corresponding to pfn.
