Are you sure the problem is because of the graphics driver, not e.g. related to the ATA error? E.g. have you tried suspend/resume with the radeon kernel driver disabled via something like radeon.modeset=0 on the kernel command line? -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
