I think, I have seen this problem in 5.x and then doing sysctl hw.acpi.thermal.tz0.active=0 followed by sysctl hw.acpi.thermal.tz0.active=-1 was the workaround. I am running -CURRENT now and I don't see this problem. However, ability to force active cooling level seem to disappear as well ;) Output of sysctl -a hw.acpi.thermal right after boot will help as well as your ASL dump (see Handbook for directions on how to get one). -- Alexandre "Sunny" Kovalenko (Олександр Коваленко)
