I'd like to perform a bisect to identify the Ubuntu specific commit that introduced this. First can you test the Zesty and Artful kernels to see if the bug has already been fixed in the newer releases? If it has, we can focus of finding the fix with a "Reverse" bisect.
The kernels can be downloaded from: Zesty: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/13563574 Artful: https://launchpad.net/~canonical-kernel-security-team/+archive/ubuntu/ppa2/+build/13567624 To install the kernels, just be sure to install both the linux-image and linux-image-extra .deb packages.
