I have installed and tested with 3.19.0-30-generic (and 3.16.0-50-generic, what I had before) and neither have them have solved the problem. Still when I try to shutdown, the system reboots only. Sometimes now it will reboot without my USB mouse / keyboard working. I'm not sure why, or which kernel, but it did happen once or twice. If hard reset / shutdown they come back. It's probably an unrelated quirk, but I like to mention everything I notice since I know what debugging is like.
