After a few day (but can be a short time), powernowd or the ondemand governor doesn't work anymore. The cpu frequency can't be changed. I can unload the longhaul module but, after modprobe longhaul fail (not found on my system). I have to reboot. /var/log/message: Dec 18 05:01:09 www -- MARK -- Dec 18 05:21:09 www -- MARK -- Dec 18 05:41:09 www -- MARK -- Dec 18 06:01:09 www -- MARK -- Dec 18 06:02:05 www kernel: [379334.212264] longhaul: Failed to set requested frequency!
