Sounds like it may be http://lkml.org/lkml/2008/2/17/78.
Suggest you try reverting that before doing the bisect.

This is probably fixed by:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=00e962c5408b9f2d0bebd2308673fe982cb9a5fe
As this is on the regression list, Kamalesh, can you please confirm
it's fixed now?
