The exact location of the crash was xen/include/xen/mm.h:188 in
page_list_add_tail()

static inline void
page_list_add_tail(struct page_info *page, struct page_list_head *head)
{
    page->list.next = PAGE_LIST_NULL;
    if ( head->next )
    {
         page->list.prev = page_to_pdx(head->tail);
         head->tail->list.next = page_to_pdx(page);  <--- crash on this
line.
    }
    else
    {
        page->list.prev = PAGE_LIST_NULL;
        head->next = page;
    }
    head->tail = page;
}
