Hi,
Problem description: Oops occurs randomly. It is pretty much reproducible when gnome-shell is used. It occurs as soon as any applications in gnome-shell is started. It does not occur with xfce without compiz. It occurs if xfce is used with compiz and few effects are enabled. Please see attached photo. I have also attached output of lspci -vvv as root.
