If I try to restart gnome-shell or gdm after this all I get is the following message. Everything does work fine on initial boot up until I suspend. intel_do_flush_locked failed: Invalid argument Booting on the 3.13 kernel from trusty, this problem does not occur. I also tried to test utopic dailly Ubuntu GNOME, this fails to even boot too gdm, unless I set nomodeset from the kernel line. I have never need to do this in the past though.
