Yes I'm using KMS when this error occours. Hardware: - Tyan Tiger K8W S8875 (AMD8151 Northbridge) - Radeon HD3650 AGP (RV635) Software: - linux-2.6.32 - libdrm-2.4.16 - mesa-7.7_rc2 - xf86-video-ati-9999 (latest git everytime) - KDE-4.3.4 with compositing enabled (OpenGL) The errors occours after a while of normal desktop work. I haven't tested without KMS or compisiting. Will do this as well. regards, Johannes ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- _______________________________________________ Dri-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/dri-devel
