I fixed something as part of the large pages work which might have also fixed this problem. However, you have CONFIG_DEBUG_VM enabled, so it would have actually triggered the bug. http://git.infradead.org/users/willy/linux-dax.git/commitdiff/2f864b6c27caa737ccfe65a86972f6b73a66a095 I don't think anything else I've changed will fix this bug, whatever it is ;-(
