Comment # 46 on bug 79980 from Lukas Kahnert

I tried to run piglit with all tests and everytime(I tried 3 times) i get a
blackscreen and the System hangs. I dont know the usage of Piglit so i cant say
on which test the GPU hangs.
It looks like the same bug which also appears randomly by watching
videos/flash.
I used the latest patch(v3).
