Hi all ,
I'm runnig FreeBSD 5.3-RELEASE #0 on an IBM Thinkpad R50p , when I run some make install in the ports distribution.
I got the following message : tornado root: WARNING: system temperature too high, shutting down soon!
After 2-3 secs the system shuts down.
when I looked in /var/log/messages after booting , I found :
Mar 2 21:24:18 tornado kernel: cpu0: Performance states changed
Mar 2 21:24:39 tornado kernel: cpu0: Performance states changed
Mar 2 21:24:39 tornado root: WARNING: system temperature too high, shutting down soon!
I was using 5.3 CURRENT ( and previous releases ) a while before , and I did not have this problem.
my first thoughts is that it is a ACIP problem. but I dont have knowledge about ACPI stuff.
I think that some parameters in hw.acpi.thermal are not correct.
hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.tz0.temperature: 3312 hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 3647 hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 3672 hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
specially hw.acpi.thermal.tz0._ACx , there is no cooling level temperatures defined.
Also , the hw.acpi.thermal.tz0._CRT: 3672 ,hw.acpi.thermal.tz0._PSV: 3647 are too close ,
the cpu don't have enough time to cool down before reaching the critical temp.
I tried debugging the ACPI module , so I compiled it with debuggin options . but the kernel could not load it and I was running without acpi.
I attached < sysctl -a > and < cat /var/log/messages >
I want to keep using ACPI , and I really need to fix this.
For any suggestions ,
Many thanks
