Xorg.0.log

I am using the KDE desktop without compositing on a Samsung P35 which has a
radeon mobilty 9600 card. Even in this case the desktop sometimes simply
freezes. No switch to a virtual terminal or killing of the xserver is possible.

I did not find anything in /var/log/messages or /var/log/Xorg.0.log.old after a
freeze.

Workaround is to boot with radeon.agpmode=-1 on the kernel command line. Then
even Desktop effects did not cause a crash so far, although they are very slow.

The bug can often but not always be triggered by opening a firefox session with
many opened tabs.

I am using openSUSE packages

Kernel: 2.6.36-rc3-10-default
xorg-x11-server-7.5_1.9.0-62.14.i586
