--- Comment #89 from agapito tcxjy@vomoto.com --- 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.
