Comment 3 for bug 1750568

I confirmed that Artful and Bionic already contain commit 903e48531e8b5d414c8f1960eacac24c31f60344, which was included in mainline as of v4.8-rc8.

The commit is not in Xenial, so I built a Xenial test kernel with a cherry pick of it. The test kenrel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1750568/

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