Created attachment 38715 [details] 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 Mesa-7.8.2-35.1.i586 xorg-x11-driver-video-7.5-88.1.i586 which has * Do Sep 02 2010 - xf86-video-ati-6.13.99 20100901-2b98ec1 * latest radeon git master driver ( 2010-09-01)

(In reply to comment #2) > Workaround is to boot with radeon.agpmode=-1 on the kernel command line. Do any other values for that option work? The valid values are 1 / 2 / 4 if your setup is AGPv2 or 4 / 8 if it's AGPv3.

Please also attach the dmesg output without agpmode=-1.

I can confim this bug on my notebook with radeon 9000 mobility. There is more annoing that after upgrade to xorg 1.9.0 radeon.agpmode=-1 stops working and my notebook became totally unusable because it freezes after a couple of minutes. I'm trying to recompile radeon module with --disable-dri but it's does not work with a lot of errors. However compiling without --disable-dri works but result is the same as with distrib drivers - freeze after 2-3 minutes of work. The more I noticed that freeze without radeon.agpmode=-1 before xorg 1.9.0 arose in scrolling context while looking webpages or javascript games. The something like that is reprodused also under WinXP while looking flash context making screen totally white a long long time ago ;) I'm using now Arch Linux i686, with 2.6.32 kernel and xorg 1.9.0 No disable font antialiasing, no disable xcompmgr helps me to make it works normally with new xorg.
