Comment 72 for bug 16873

I have an ati radeon 7000, using the "ati" driver (tried "radeon" with same results. Maybe "ati" and "radeon" refer to the same thing?), and I have DRI turned *off*. Still, my system freezes at random (i.e., no ctrl-alt-bckspace, no ctrl-alt-F?, and is unpingable from the outside).

Again, note that I do not use DRI and am still experiencing these intermittent freezes.

Some more info: I have xinerama set up, so I don't know whether this contributes to the problem. Previously, running Fedora Core 4, I had no problems with this card so I'm thinking that it has to do with some recent change to the xorg drivers.

Here are the relevant sections of my xorg.conf:
