I think I am having the same problem; seemingly randomly, the screen goes blank then flashes white vertical stripes in the top half of the screen every 3 seconds or so. I've attached output of lspci -vvnn and dmesg as per one of the first posts, as well as Xorg.0.log copied from immediately after the crash via ssh.
