Just a quick ping: is this making its way to Linus (and stable)? I've been running it for five days through (literally, due to monitor bugs) thousands of plug/unplug cycles with no ill effects. (Can we *please* get rid of, or at least ratelimit, the plugged/unplugged printk? It's taking over my logs, and I'm almost certain that it's not a driver bug.) --Andy _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
