I got oibaf ppa. They started to use LLVM 3.6 compiler around that time I
started to have unstable dota. I cant finnish any dota 2 games. The computer
hangs before 10min mark while in dota. But I have played around 2hour episode
of game of thrones from tell tale. So this sounds only dota 2 issue for me.

I could see console a message something like this:

"Still active bo inside vm" 

The computer freezes, most of the times I could only force boot.
