I can confirm that this is a very frustrating bug, and still seems to be affecting lots of us :-) Don't forget to check the upstream bug (linux-kernel-bugs #12309 - http://bugzilla.kernel.org/show_bug.cgi?id=12309). Also, I suggest keeping an eye on what sounds like promising comments on bug #131094 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/131094) regarding kernel 2.6.31.
