This gave me a WTF moment recently. MVC? Viewstate? Eh!? All was fine on the dev server, but as soon as I deployed to the web farm this error appeared every time I recycled the app pool. It turns out it was the cookie created by <%= Html.AntiForgeryToken() %> and simply generating a machine key sorted it out.
