Actually, I think this is fallout from a patch we added to automatically fall back to irqpoll mode when this happens. A few others have mentioned it's now spamming their logs. See bug 797369 for a similar comment. The patch is supposed to help some machines that have a balky pci bridge that doesn't seem to do interrupt acks correctly. It just seems a bit verbose at the moment. josh _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
