I built a test kernel with commit 2ce87cc5b269510de9ca1185ca8a6e10ec78c069. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1750441 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.
