Comment # 89 on bug 79980 from agapito

Still present in the final 3.16 kernel. This bug is really crazy. I have a lot
of hard lockups playing Age of Empires HD using windows steam. I can't provide
any log or debug info because my machine die completely.

My hardware is: Gigabyte HD 7950, using HDMI output on Archlinux + KDE + Mesa
10.2.5 + xserver 1.16.
