Then, I implemented it in our kernel as a result. : : I'll take a look at your patch. Umemoto-san is right in that you really : want the kernel to control cooling.

I keep getting the system shutting down on my HP by FreeBSD because the temperature exceeds the _CRT value. Maybe there's something wrong with my values, since it happens a lot: hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 0 hw.acpi.thermal.tz0.temperature: 0.0C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 90.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 94.0C hw.acpi.thermal.tz0._ACx: 40.0C -1 -1 -1 -1 -1 -1 -1 -1 -1 Note: temperature is always 0.0C. What can I do to help my situation, if I really want the kernel doing the cooling?
