Ou sorry, 6.0 RC1 (cvsuped yesterday)

I saw the thread and I've the same problem. I can't change the value
of hw.acpi.thermal.tz0.active ( I tried every value between -1 and
10).

> sysctl -a hw.acpi.thermal 
(http://aucupor.gmxhome.de/hw.thermal.txt)

hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.tz0.temperature: 38.8C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 85.8C
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 104.8C
hw.acpi.thermal.tz0._ACx: 64.8C 49.8C -1 -1 -1 -1 -1 -1 -1 -1

I've uploaded it to: http://aucupor.gmxhome.de/acpidump.txt.

Many thanks,
