Would it be possible to test a couple of kernels? First test the latest Xenial kernel: https://launchpad.net/~canonical-kernel-security-team/+archive/ubuntu/ppa/+build/12080749
If that kernel still has the bug, please test the last kernel version before you hit the bug, -58: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/11758956 For both these kernel, you need to install both the linux-image and linux-image-extra .deb packages.
