I´ve seen this now with several radeon based cards (radeon mobility M6 and radeon 9250) and the "radeon" driver on x.org 6.8.2 (Suse 10.0) When I run glxgears sometimes after about 10 seconds the whole system crashes. I´m not even able to move the mouse, the reset button is the only option :( Is this a known bug? regards Michael
