Bill Irwin has told me about a rare bug with exec() mapping garbage into the address space of a process, which might trigger this bug check the next time that process exec()s. I've gotten two reports of this bug now, but have no idea what particular combination of hardware / compiler / config triggers the bug. The rmap code seems to have survived akpm's stress tests so it's probably not a simple bug to track down ;/ regards, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
