Hi My laptop freeze when I enable DRI in my XF86Config-4 I am using Debian sarge and Xfree86 4.3. If it can helps, my laptop is a compaq evo N160 with a blazing fast mobility radeon M6 8Mb DDR. What I tried : -Kernel 2.6.8 to 2.6.11 -testing and unstable debian packages xserver-xfree86 -a lower resolution -I also tried the dri-trunk unofficial debian package to get drivers from Xorg The problem : My computer boot and get to the KDM login screen. From there I can either start KDE or hit ctrl+alt+f1 to open a terminal. When I launch KDE, it freezes a few seconds later. When I open a terminal, it works, but if I go back to KDM, it also freezes. The freeze It is not a constant thing. Most of the time I can move the mouse and connect by ssh, but that's all. I can't click on anything and the keyboard doesn't work. The image can be corrupted. What I know is that Xfree86 process takes 99% of my CPU at this time, and it is impossible to kill (even with -9). The reboot command doesn't work. I know the problem comes from DRI because if I comment it in my XF86Config-4, everything works. my config files are at http://yolagang.servebeer.com/bug

Apparently, you didn't read the top of the log file you attached... anyway, does it also happen without Option "AGPMode"?
Try getting the DRM from CVS and using it - 2.6.12 will have a fixed DRM for X4.3, simple patch just got missed, I might push it into a 2.6.11.7 depends on if I get time..
option agpmode=4 was the problem
