Testing 4.4-rc6 had the difference in result that after the fan went on max speed (unlike when booting on 3.19.0-25) and hdd was working - after a while the blue XUbuntu screen with the spinning wheel came up. After that the screen went black again and hdd stopped.
4.3.3 was same result but without the blue XUbuntu screen.
