Hello, I'm running Debian Unstable on my laptop and have a question about trip points in ACPI thermal zones. My laptop gets too hot very quickly, for example when I compile a kernel, or in font generation during installation of a latex font. This causes the laptop to shutdown. On my laptop (Asus L8400K) the trip points are: # cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 80 C passive: 70 C: tc1=3D1 tc2=3D4 tsp=3D300 devices=3D0xc127cb= 60 active[0]: 60 C: devices=3D0xc127b800 When I set them to the following I get much better results and it doesn't get overheated much. # echo -n "80:0:60:55:0" > /proc/acpi/thermal_zone/THRM/trip_points # cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 80 C passive: 60 C: tc1=3D1 tc2=3D4 tsp=3D300 devices=3D0xc127cb= 60 active[0]: 55 C: devices=3D0xc127b800 But, for some reason, the trip points get reset every now and then (usually within 30 mintes or so, don't know the exact interval). Does anyone know what causes the trip point setting to be reset? I'm using debian kernel 2.6.14 from unstable. I attached the dmesg, dmidecode, acpidump, lspci and interrupts output. Thanks, Olaf |
