I am experiencing some of the same problems as reported by Hife above. The disabled network problem doesn't happen every time I wake my machine up, but on some of the occasions when it does I also find that sleep is disabled from the menu and from the function key, although I can still "sudo pm-suspend" from the terminal.
Rebooting from the Unity pull-down menu seems to be permanently disabled, regardless of whether networking or sleep are working, so I don't know if this is part of the same problem.
