Hi! The ACPI thermal zone does not work properly on my ASUS A8N-E (nForce 4 ultra). It always shows the temp as 40C: zeus> sysctl hw.acpi.thermal hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 0 hw.acpi.thermal.tz0.temperature: 40.0C 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: 73.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 75.0C hw.acpi.thermal.tz0._ACx: 73.0C -1 -1 -1 -1 -1 -1 -1 -1 -1 mbmon however shows sane (well, changing at least :-) ) numbers: zeus> mbmon -c 1 Temp.= 35.0, 25.0, 37.0; Rot.= 1480, 0, 6026 Vcore = 1.12, 0.00; Volt. = 3.30, 4.92, 11.67, -10.24, -0.00 I suppose this is no fault of FreeBSD at all, but with the ASL: http://www.sics.se/~bengta/FBSD/a8n-e.asl I am quite clueless when it comes to ASL, but the RTMP method does have a case when it returns the constant 0x0C3C, which I believe evaluates to 40C (/10-273.2). There is also another RTMP method as part of a device "ASOC" which seem to support reading not only CPU temp. The ASOC device seems to provide access to a lot of MB sensors. I don't have a thermal problem, but it would be nice to have the thermal zone working! Any clues if it is easy to fix? (The problem seem similar to: http://lists.freebsd.org/pipermail/freebsd-acpi/2006-May/002724.html but unlike this post, the _TMP is not a no-op) Regards, Bengt
