I haven't had any persistent problem like this but occasionally I've had a shutdown / restart command have trouble. I usually login to the shell using ssh from another computer and look at the active processes. I look for application processes first as they should have quit. If I can't quit it from the GUI then I kill it using the shell. Then I start looking for other processes that might be holding things up. If all else fails I use the shell shutdown command. While the above process is aimed at restarting / shutting down the computer it can also help to determine the cause of hangs like this.
