Droid Maxx won't shut down

[pleitter]

Pressed the button to shut down my phone, and I've been seeing a "dialogue box" that says Power Off, Shutting down, with a spinning circle -- this has been going on for over 20 minutes. Ideas?

Hold power and down volume for like 10 seconds if you want to force it to shut off.
