Public bug reported: For about two weeks (I assume one of the driver updates caused the problem), the Intel GPU X driver crashes several times during a session. Several times a day, a hard reboot is necessary since everything but the mouse cursor freezes. It is also not possible to switch to text consoles via Alt-F keys.
It is a particularly severe bug, because it results in system freezes and therefore in data loss. It happens in Gnome 3 Shell and also in Unity. I also cannot associate the Intel GPU driver crash with any particular activity. Sometimes it even crashes without having done anything. I hope the attached log files will help to find the problem and to fix it. If you need more information, I am more than willing to provide additonal tests.
