And what is userspace going to do with this noise? Is this an error? Just normal operation? A device should never be saying anything to the log for normal boot functionality. When is this called? And no need for the "cpu_capacity:" right? Shouldn't the pr_info() line handle the prefix for you? thanks, greg k-h
