Better report it to kernel bugzilla, it is better for tracking.
(Also see https://bugzilla.kernel.org/show_bug.cgi?id=17892 )

Anyway, there are some patches waiting for inclusion in DM tree
for weeks and all fixes must follow these changes. Also replacing
io barriers in 2.6.37 can interfere here (fsync uses barriers).

Anyway, if you have some tests which you found useful for dm-crypt
testing, attach them to bugzilla too. I would like them to run
for all kernels in the future to avoid performance regressions.
