    Since a couple of days, when I want to awake my uMBP (15 inch) from sleep modus, the screen remains black (happened 2 times). Another issue that occurs is that I get a square on my screen that says (in a couple of languages) that I have to reboot my Mac, so it hangs again.

    This is the report I get:

    Interval Since Last Panic Report: 36136 sec
