Comment 13 for bug 116456

Having the same problem here on an iBook 900. I think this bug is related to X, because when I get this lockup, I can still ssh into my machine. When I run top through ssh, X is maxing out my cpu... Strange thing is I can't kill it either; it just keeps running. So I have to reboot over ssh. Just yesterday I've disabled everything "exotic" ( read composite stuff ) in my xorg.conf to see if that makes this bug go away. I don't know to much about x, so maybe I'm a bit cryptic in my descriptions, but please ask if I need to supply more info.
