I built the next test kernel, up to the following commit: 7dc603c9028ea5d4354e0e317e8481df99b06d7e
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1627108/7dc603c9028ea5d4354e0e317e8481df99b06d7e Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

I was using 4.4 on Xenial a few days ago and everything was working just fine. Installed Yakkety and this issue happens. I will downgrade the kernel and see if that mitigates the issue.
