I'd like to build some test kernels, each with peeling of one of these commits at a time to try and narrow down which one caused it. I built the first test kernel with commit a010365 reverted. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1699772 Can you test this kernel and see if it resolves this bug? Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages.
