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.
