That's not exactly being the 'culprit', it's simply doing what it's supposed to do. You probably don't really want your CPU to run at 2.2GHz all the time, it'll get hotter and eat more power for no good reason. As long as it scales to 2.2GHz when you actually need the power, that's sane... -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
