Comment 14 for bug 1573231

I built a test kernel with a revert of 1f12e32f4. To revert this commit, I also had to revert e7ee3e8, 2d4de83, 87f01cc and 33c3cc7

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1573231/

Can you test this kernel and see if it resolves this bug?
