Comment # 151 on bug 79980 from initzero@gmail.com

Same issues with my OLAND card here.
Archlinux, Mesa 10.3, Xorg 1.16.1 and Radeon 7.5.0.

Kernel 3.14.20 is still stable, 3.16.X and 3.17 may run for approx. 1hr and
finally crash during normal desktop usage (Gnome 3.14 + Browser + ...). Didn't
check 3.15 recently.

Sooner or later someone needs to bisect that sucker! :)
