hi again, Lars,
No luck. I commented out:
cpufreq_load=3D"YES"
from /boot/loader.conf.local
and added=20
powerd_flags=3D"-a adaptive -b adaptive"
to my rc.conf (I already had powerd_enable=3D"YES".
I rebooted the computer and went to the garage to get something. I came back
after what must have been less than 5 minutes. I saw GDM close and the lapt=
op
shut down with CRIT temperature alert.:
Oct 8 20:14:30 ayiin root: WARNING: system temperature too high, shutting =
down soon!
Oct 8 20:14:40 ayiin kernel: acpi_tz0: WARNING - current temperature (99.0=

There were a couple of lines about something to do with _thermal, but it wa=

full shutdown mode and couldn't catch them. they are not showing in the log=
s.
/var/log/messages shows the machine was up for under 2 minutes. I don't run
anything on boot that will burn CPU (seti,etc... only on request, it was
definitely not running)

well, i can barely hear the fans at all. I am not sure if this is how it's
supposed to be for Thinkpads... I will check regardles... but it seems to w=

somewhat (i'm down to 57C now...)

I am running it now again with cpufreq and powerd, with the flags as you sh=
ow.

I am happy to keep trying / digging / getting some logging happening of
temperature and... system load/cpu frequency? not sure what would be useful.
Things i was thinking could help with this is tweaking of the _ACx and C1
values... but i'm not sure how to go about them...
Not sure if it's relevant, but i have APIC disabled (ACPI is on, APIC is of=
f).
I'm happy to RTFM....but i don't know where that is :)
cheers,
B
