Subject: next-20130607 BUG: Bad page state in process systemd pfn:127643
(This may or may not be collateral damage from my previous e-mail
regarding a BUG at lib/idr.c:424)
Saw several of these booting next-20130607 before it even got to
a single-user prompt. -0603 is OK, so whatever did it is a recent patch.
Several people touched mm/page_alloc.c on 06/07, have CC'ed them.

Hit a whole stream of these - identical tracebacks for different pfn's.
Almost continuous and in order, but not quite.
