dmesg

Screen freezes for few seconds and then display switches off.
It switches on and off randomly after this.
Xorg is stalled, sometimes you lucky enough to switch to console.

Looks like triggered by firefox.

Arch Linux
Xserver 1.16.1, Mesa 10.3.2, Linux 3.17.2 (but it happened with previous versions too).

Probably a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=85647

After Xserver and Mesa update the issue went away.
