Holger, this looks like a race condition when allocating a compound page, did you only see it once or is it actually reproducible? I think this happens when a new compound page is allocated and PageBuddy is cleared before prep_compound_page() and then we see PageTail(p) set but p->first_page is not yet initialized.

* [patch -mm] mm: close PageTail race 2014-02-05 8:42 ` Michal Hocko @ 2014-02-12 9:00 ` David Rientjes 0 siblings, 0 replies; 13+ messages in thread From: David Rientjes @ 2014-02-12 9:00 UTC (permalink / raw) To: Andrew Morton Cc: Andrea Arcangeli, Mel Gorman, Rik van Riel, Kirill A. Shutemov, linux-kernel, linux-mm Since "mm, compaction: avoid isolating pinned pages", it has been possible for page_count(page) to race with prep_compound_page() by finding PageTail(page) set with a NULL or dangling page->first_page. "mm, page_alloc: make first_page visible before PageTail" adds a store memory barrier to prep_compound_page() to ensure page->first_page is set, but nothing is preventing compound_head() from seeing a dangling head page. This patch uses Andrea's implementation of compound_trans_head() that deals with such a race and makes it the default compound_head() implementation. This includes a read memory barrier that ensures that if PageTail(head) is true that we return a head page that is neither NULL nor dangling. This is the safest way to ensure we see the head page that we are expecting, PageTail(page) is already in the unlikely() path and the memory barriers are unfortunately required. Hugetlbfs is the exception, we don't enforce a store memory barrier during init since no race is possible.
