The fan control has no been fixed by my DSDT. The /proc/acpi/fan is empty= . I put the "cookbook" for debugging my DSDT, perhaps you can have a look a= t it to see if something is wrong. The folder /proc/acpi/thermal_zone/THRM has: ----------------8<---------------- #cat /proc/acpi/thermal_zone/THRM/cooling_mode cooling mode: passive #cat /proc/acpi/thermal_zone/THRM/polling_frequency polling frequency: 30 seconds #cat /proc/acpi/thermal_zone/THRM/state state: ok #cat /proc/acpi/thermal_zone/THRM/temperature temperature: 44 C #cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 97 C passive: 85 C: tc1=3D2 tc2=3D3 tsp=3D40 devices=3D0xdfc07= 168 ---------------->8---------------- The fan module is present: ----------------8<---------------- # lsmod | grep fan fan 6020 0 #zgrep -i fan /proc/config.gz CONFIG_ACPI_FAN=3Dm ---------------->8---------------- At the boot, the fan doesn't start immediately, then it start at fisrt speed. After a moment the fan rotates at full speed, but never goes down, even if the temperature is 44=B0C. The CPU is not at full speed (max:2000MHz): ----------------8<---------------- #cat /proc/cpuinfo | grep "cpu MHz" cpu MHz : 798.354 ---------------->8---------------- Any ideas?
