Starting powerd. powerd: using sysctl for AC line status powerd: using devd for AC line status load 77%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 74%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 78%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 79%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 65%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 72%, current freq 2400 MHz ( 0), wanted freq 2400 MHz load 76%, current freq 2400 MHz ( 0), wanted freq 2400 MHz ... The real load was between 3 and 7 % while these were recorded. Note that I use the normal/old adaptive mode.
