--- Please enter the report below this line. ---
i am unable to set the temperature of the passive trip point in the thermal 
module.

laptop:/proc/acpi/thermal_zone/TZ1# cat trip_points
critical (S5):           75 C
passive:                 75 C: tc1=1 tc2=2 tsp=100 devices=C000
active[0]:               65 C: devices=C1D7
active[1]:               60 C: devices=C1D8
active[2]:               46 C: devices=C1D9
active[3]:               40 C: devices=C1DA

laptop:/proc/acpi/thermal_zone/TZ1# echo -n "75:70:65:60:46:40" > trip_points
bash: echo: write error: Input/output error

(for now, i change cpu frequancy to lower cpu temperature with acpi 
temperature events and a bash script)
