Is there a special reason why you suggested the value 91? Because I added thermal.crt=99 as I saw it on some occasion on my system. Now I get: # acpi -V Thermal 0: ok, 64.0 degrees C Thermal 0: trip point 0 switches to mode critical at temperature 99.0 degrees C Thermal 0: trip point 1 switches to mode passive at temperature 105.0 degrees C and acpitz-virtual-0 Adapter: Virtual device temp1: temp1_input: 66.000 temp1_crit: 99.000 coretemp-isa-0000 Adapter: ISA adapter Physical id 0: temp1_input: 66.000 temp1_max: 86.000 temp1_crit: 100.000 temp1_crit_alarm: 0.000 Core 0: temp2_input: 63.000 temp2_max: 86.000 temp2_crit: 100.000 temp2_crit_alarm: 0.000 Core 1: temp3_input: 66.000 temp3_max: 86.000 temp3_crit: 100.000 temp3_crit_alarm: 0.000 pkg-temp-0-virtual-0 Adapter: Virtual device temp1: temp1_input: 67.000 Thank you for your kind help, Thomas -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
