I do not know if it is the same bug that I have, I don't have the drmRadeonCmdBuffer message in dmesg, but I have many of the above described simtomes:
1) With disabled desktop effects windows refresh and scroll is very slow; 2) enabling desktop effects improves speed, but makes xorg crash and hang after a while, sometimes with the appearance of unreadable graphics on the screen, or black screen and hang without the possibilty to Ctrl+Alt+F1 to go to a console. 3) With desktop effects activated the crash appears quickly by simply running glxgears at fullscreen an by trying to make change the view on gears with arrow keys This is my system configuration: Asus A2500D Laptop AMD athlon XP-M 2800+ RAM DDR333 1024Mb ATI Mobility Radeon 9200 I attach my dmesg and Xorg.0.log if it can help ** Attachment added: "dmesg.txt" http://launchpadlibrarian.net/48389413/dmesg.txt -- [Radeon kernel module] drmRadeonCmdBuffer: -12.
