uMBP - Hangs and needs reboot

[Weirddoc]

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:

Anyone knows how to solve this issue?? Thanks.

This is not the problem. Booting works fine. I want to know the reason why my mac stops working, why it hangs?

Yea but do those simple steps. They can fix the issue, that's why. Linked that guide because I'm too lazy to type
