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 kernels and post back? http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.8-ckt1-wily/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.8-ckt2-wily/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.8-ckt3-wily/ You don't have to test every kernel, just up until the first kernel that has this bug.
