dmesg from linux 3.16-rc6

So, this was never closed as fixed...

I sometimes experience hangs too up to linux 3.16. I looked at the stacktrace
and to my untrained eyes it looks mostly similar.

ivy bridge with upstream 3.16-rc6, xorg 1.16 and xf86-video-intel git master
with sna, rendernode and tearfree.

Symptoms: Xorg display randomly freezes. Changing num status led on the
keyboard still works. Switching to a tty with ctrl+alt+f2 switches my (primary)
laptop screen to a black screen. The external DVI(=HDMI) monitor stays at
displaying the stuck Xorg content. After a while this message appears in dmesg
and the system recovers and is usable without issues again. I am pretty sure
this only happens when an external monitor is attached.

Sorry if this is something else, but it looked similar enough.
