Unfortunately, in the environment we have, the latest we can run is 2.6.32.xx (IB drivers, filesystem modules, etc.), so even if I installed it, I wouldn't be able to use NFS). I can verify that I added the patch from that commit into 2.6.32.24-generic and the problem disappeared. When we booted back into the stock 2.6.32.24-generic, it reappeared.

Sorry.
