FYI, this also affects Saucy with 3.8.0-30-generic and Mesa 9.2.1 and Intel DRI 2.99.904. Also I observed that with switching to Mesa 9.2 the number of lockups highly increased. Additionally with newer drivers installed, there are now complete system lockups anymore. Just the VT switching, which is still very annoying in games.
