Disabling in BIOS doesn't made any difference. The errors were still reported. Your patch disabled it. But I think this will make work harder for driver developers as they won't get this error anymore. Could this be made changeable on runtime/boottime? I've added drm people to CC as they're responsible for this error. 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 Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
