HI all, I am running SUSE 10.0 and the following messages appear repeatedly in /var/log/messages: ... Aug 27 14:00:59 obelisk kernel: ACPI-0212: *** Warning: Device is not power manageable Aug 27 14:00:59 obelisk kernel: ACPI-0629: *** Warning: Unable to turn cooling device [dffe9cc0] 'on' ... I traced this to the fact that acpi thinks the machine is running too hot and is trying to turn on the fan: $ cat /proc/acpi/thermal_zone/THRM/temperature temperature: 72 C $ cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 100 C passive: 50 C: tc1=4 tc2=3 tsp=60 devices=0xc189f7c0 active[0]: 50 C: devices=0xdffe9cc0 $ cat /proc/acpi/thermal_zone/THRM/state state: passive However, there is no way that the machine is really at 72 deg. C. There is ample cooling and while running in BIOS setup, it shows less than 40C CPU temp and less than 35C motherboard temp. Clearly the ACPI subsystem is confused about the actual temperature. The machine is a AOpen XC-cube model EZ661-T with a 2.6GHz Pentium 4 and 1GB of memory: http://xc.aopen.com.tw/CubeProduct_01.aspx?Auno=12&mdstyl=25 I _could_ unload the "thermal" kernel module and get around this problem but ideally I'd like to have the proper temperature reading from acpi as well as from lm-sensors. Does anyone know of a "fix" to make this right? -Ti
