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.
