Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

I built a test kernel with the patch. It can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1200570/

Can you test that kernel and post back if it has this bug or not. Note, you will need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

Saucy will pick up this fix when it is rebased to v3.11-rc2. I'll submit this for inclusion in Saucy, until it is rebased.
