Ha ha! For years I had wrong misconfigured critical-min with corresponding critical-under powerd command. I thought this was some recovery mode for when was previously overheating ... that is it is now "under" the critical temperature.
Current CritMax WarnMax WarnMin CritMin Unit [amdtemp0] CPU0 Sensor0: 64.750 92.000 85.000 degC CPU0 Sensor1: 67.500 92.000 85.000 degC CPU1 Sensor0: 63.500 92.000 85.000 degC CPU1 Sensor1: 65.750 92.000 85.000 degC I know about the "normal" powerd command, but I also used envsys critical-min and powerd critical-under to adjust my cpu frequency as if the system was no longer too hot. So my logs often logged "dropped below critical limit" and my cpu frequency was always at that setting (and never what I had for "normal"). Thanks for this thread now I know there are warning and critical settings for too cold.
