I have exact same experience on a Lenovo Notebook (6 years old and always running Ubuntu) with Nvidia proprietary graphics driver. With 12.04 it was perfectly fine. Now since 14.04 I experience same as Jaap Woldringh (jjhwoldringh) wrote on 2014-09-14:
the shutdown halts halfway, I guess after the hard disk stops rotating (noise stops), but the cooling ventilators still run.
