I think it must be the last as Martin doesn't mention a framebuffer device at all and it doesn't seem to happen with 4.2 for him. That's very interesting; someone 'only' needs to look at a diff between the radeon driver in 4.2 and 4.3 and see what was changed that's also done in radeonfb. ;) I used to have the problem on a PowerBook with an M7, but not with an M6 or an M9. I guess it's a semi-random (timing related?) bug influenced by many factors. -- Earthling Michel D�nzer \ Debian (powerpc), XFree86 and DRI developer Software libre enthusiast \ http://svcs.affero.net/rm.php?r=daenzer _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
