Normally I'd agree (I understand what the code does), but I don't have any errors - and all sysfs entries! - after boot, so as far as I can tell the flag isn't set properly even after a successful boot, and then leads to spews on resume. Maybe the entire process is racy somehow? My card is an admittedly old, but perfectly working fanless (!) HD 5500, 1GB RAM, driver is r600 and everything - including dpms, suspend/wakeup etc. works fine. I tried to disable dpm on boot and that of course stopped the warnings, but then the card was constantly at ~55° instead of the usual ~45°, for no noticeably win in performance. If you have any other suggestions or patches for me to try I'd be glad to test/verify. In the meantime I think setting the flag is the easiest fix; it certainly works for me. Thanks for looking into it! cheers Holger _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
