Is you select 4.4.0-15 from GRUB menu it boots, correct?
We should be able to perform a kernel bisect to narrow down the commit that introduced this regression. We first need to identify the last good kernel version and the first bad one.
Can you test the following upstream kernels:
4.4.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.6-wily/ 4.4.15: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.15/ 4.4.50: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.50/
