I'd like to perform a kernel bisect to figure out which commit caused this regression. We need to identify the earliest kernel that did not exhibit the bug and the first kernel that did exhibit the bug.
Can you test the following upstream kernels and post back? v4.4.19: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.19 v4.4.20: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.20 v4.4.21: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.21 You don't need to test all of them. Just up to the version that first exhibits the bug.

It will keep loading the purple Ubuntu "dots" loading screen for ages and stay there. There is no issue rebooting back with kernel 4.4.0-38.57.
