Ubuntu 15.10 hangs on shutdown with both generic and lowlatency kernels. In order to shutdown without forcing by pressing long on the laptop button, I need to restart, and then to shutdown, and then the shutdown takes more than a minute, which isn't the case with 14.04 which shutdowns in just few seconds. This happens with both fresh install and updated system.
