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.
