No need to send v5, done! I have a system that appears to be affected by this bug: kepler:~> lscpu | grep -i mhz CPU MHz: 4000.000 CPU max MHz: 7140.6250 CPU min MHz: 2200.0000 So I should be able to confirm after a reboot.'CPU max Mhz' seems to be saner now: kepler:~> lscpu | grep -i mhz CPU MHz: 2200.000 CPU max MHz: 4917.9678 CPU min MHz: 2200.0000
