I have no problems running X under the 2.6.6 kernel (built from Debian sources). However when I start it under a 2.6.7 kernel (built from vanilla sources) there is a black screen when X starts and the computer is freezed (I am not even able to switch to a console). I believe that this might be related to the radeon drm: - when I use the vesa driver or when I disable the hardware acceleration (NoAccel option), X starts correctly; - when I enable hardware acceleration but I comment the line which sets AGPMode to 4, X runs correctly for about 20 seconds an then freezes (I cannot switch to a console and the SysRq are the only things left to do); - when hardware acceleration is activated and AGPMode is set to 4 X freezes immediately. Top shows that XFree86 takes more than 95% of the processor. I have put some files (syslog, XFree86.log, etc) which might be of interest for you here: http://perso.ens-lyon.fr/samuel.mimram/radeoncrash/ Feel free to tell me if you want me to do some experiments, etc. Thanks, Samuel.
