If you're running 4.1, this is probably because the chip can hang when a bus mastering operation is active while it's being reset in the course of switching the CCE on or off. This isn't an issue anymore with current CVS as it uses the CCE exclusively when DRI is enabled. That's why I only committed it to the DRI CVS once that change was made there. -- Earthling Michel D�nzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
