Howdy,

I'm running:
Linux box0 3.12.13-gentoo #2 SMP Sat Mar 29 22:38:01 EET 2014 i686
Intel(R) Pentium(R) Dual CPU T3400 @ 2.16GHz GenuineIntel GNU/Linux

My '/var/log/rc.log' says:
 * Loading module x86_pkg_temp_thermal ...

 [ !! ]

'modprobe x86_pkg_temp_thermal' says:

I found 'CONFIG_X86_PKG_TEMP_THERMAL=m' in .config for my current kernel
only.

Does the output above mean that my CPU doesn't support this feature, and
as such should be disabled in my kernel config?

Thanks.

Hi Alexander Kapshuk,
You probably don't need that module.
Grep your dmesg for therm|thermal. You should see ACPI registering
your thermal zones:
[    1.424899] thermal LNXTHERM:00: registered as thermal_zone0
[    1.424944] ACPI: Thermal Zone [TZS0] (32 C)

then look for them in:
/sys/class/thermal/
/sys/bus/acpi/devices/LNXTHERM:00/thermal_zone/temp

if not check your kernel config for needed options like:
CONFIG_ACPI_THERMAL=y 

Regards,
Dragostin Yanev

Thanks for your prompt response.

Here's the output of the commands you suggested running. Seems similar
to what you put in your email.

grep -i therm dmesg
[    0.003175] CPU0: Thermal monitoring enabled (TM2)
[    1.285152] thermal LNXTHERM:00: registered as thermal_zone0
[    1.285320] ACPI: Thermal Zone [TZ01] (57 C)

ls /sys/class/thermal
cooling_device0  cooling_device1  thermal_zone0

cd /sys/class/thermal/thermal_zone0

ls
cdev0          device  subsystem         trip_point_1_temp
cdev0_trip_point  mode      temp             trip_point_1_type
cdev1          policy  trip_point_0_temp  type
cdev1_trip_point  power   trip_point_0_type  uevent

ls -l /sys/bus/acpi/devices/LNXTHERM\:00/thermal_zone/temp
-r--r--r-- 1 root root 4096 Apr 13 15:14
/sys/bus/acpi/devices/LNXTHERM:00/thermal_zone/temp

grep CONFIG_ACPI_THERMAL /usr/src/linux/.config
CONFIG_ACPI_THERMAL=y

So I guess I'll go ahead and set CONFIG_X86_PKG_TEMP_THERMAL=n.

Thanks.

I don't think the kernel should be attempting *itself* to load this module if it doesn't detect said hardware.

Is it possible this is mentioned in /etc/modprobe.d/ or somewhere?

I'd grep /etc before recompiling my kernel, on this one.

Stroller.

Thanks for your input.

x86_pkg_temp_thermal is not found either in filenames, nor in the files
themselves residing in /etc.

I've set CONFIG_X86_PKG_TEMP_THERMAL to 'n' in my kernel config file,
and recompiled the kernel.

Everything seems OK so far.
