Description

Hello.

I noticed heating problem on Thinkpad T410, on PC-BSD 10-STABLE-p3. If I will keep system idle, after turning off nepomuk, the parameters are following:

~% sysctl hw.acpi.thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.user_override: 0
hw.acpi.thermal.tz0.temperature: 60.0C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.passive_cooling: 1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 95.5C
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 100.0C
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
hw.acpi.thermal.tz0._TC1: 5
hw.acpi.thermal.tz0._TC2: 4
hw.acpi.thermal.tz0._TSP: 600

But if I will turn on nepomuk and do anything which require more processor's power temperature quickly raises to:

hw.acpi.thermal.tz0.temperature: 95.0C
and then it jumps to
hw.acpi.thermal.tz0.temperature: 128.0C
and system is shutting down:
Nov 17 23:21:51 volkov devd: Executing 'logger -p kern.emerg 'WARNING: system temperature too high, shutting down soon!''
Nov 17 23:21:51 volkov root: WARNING: system temperature too high, shutting down soon!
Nov 17 23:22:01 volkov kernel: acpi_tz0: WARNING - current temperature (128.0C) exceeds safe limits

Laptop is "quite new" - ~2 years old. Problem didn't appear on PC-BSD 9.x branch , Windows, Linux, etc. I encountered it only on fresh PC-BSD/FreeBSD.

~% uname -a
FreeBSD volkov 10-STABLE-p3 FreeBSD 10-STABLE-p3 #19 5be16d0(stable/10): Thu Nov  7 20:29:44 EST 2013     root@avenger:/usr/obj/pcbsd-build10/fbsd-source/src/sys/GENERIC  amd64

Do you have any idea what can be the source of the problem?
