Display freezes once or twice a day (have seen it mostly when using chrome), mouse can be moved but not able click on anything. Further when the issue occurs not able to switch to terminal (Ctrl + Alt + F1). Issue started occurring only after a Ubuntu update (Kernel 3.2.0-39+). If any ssh logs or more debugging is needed please request.
