I think I'm experiencing a race condition: Irregularly my kernel runs

FYI, there are similiar reports on the net, going as far back as May 2006:
http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/1636 is the oldest one I could find.

Bugzilla entry: http://bugzilla.kernel.org/show_bug.cgi?id=7388

I, too, ran into the bug and failed to reproduce it. However, it might be worth knowing that the system went to 100% iowait afterwards.
