Comment 8 for bug 409797

I can confirm, but only xorg uses high CPU. It makes it impossible to use the computer, as gnome-screensaver never prompts me to enter my password. All I see is a blank/black screen (which is my screensaver) along with a mouse that will move sporadically if I move it. If I press ctrl+alt+f1 and wait about a minute, I eventually get access, run top, and see that xorg is using 100% cpu. Nothing else looks abnormal.

I've attached the output of lspci -vvnn

I'm on a lenovo thinkpad w500, on Karmic x64 (beta), but it also happened in Jaunty.
