Hello everybody!
Since the update from 6.2-STABLE to 7.0 I'm encountering problems with the
temperature of my Thinkpad X60s. Under heavy load, e.g., make builworld or
compile gcc or... I get the following output in /var/log/messages:
Dec 29 01:53:13 delta1 root: WARNING: system temperature too high, shutting
down soon!
Dec 29 01:53:13 delta1 syslogd: /dev/:0: No such file or directory
Dec 29 01:53:23 delta1 kernel: acpi_tz0: WARNING - current temperature (
128.0C) exceeds safe limits
Dec 29 01:53:24 delta1 syslogd: exiting on signal 15
So far so bad. Interestingly I can put money on it overheating when running
KDE "on the side". Shutting KDE down and doing, e. g., make builworld
in
tty0 helps and the "job" gets finished. Still the CPU gets some above
90
degrees hot.
To my best knowledge I haven't found any case filed in FreeBSD's
mailing lists. But I have found an issue reporting problems on
linux LKML. Exactly the same behaviour ( http://lkml.org/lkml/2007/4/2/11 ),
don't know whether this helps anyone. Also in "normal" work I
think above 60
degrees as hw.acpi.thermal reports is too high...
I should perhaps mention that the fan does work. ACPI also puts its rpm's up
a little bit. But it is just too slow in general, I assume.
Booting without acpi does not solve the problem since it just does not boot.
I have also little interest in working without acpi. dmesg shows the
following for acpi, this is the only time it mentions a failure.

The notebook is changed a little (Intel WLAN chip changed
to Atheros, 80 GB Fujitsu HDD chaged to 160 GB WD), both changes have
put the temperature up a little bit, at least the ath-chip definitely.
Attached you find the ASL. I hope I have provided enough informations,
if something is missing please let me know.
Thanks in advance,
Johannes Dieterich
PS it does not depend on whether the notebook is in the docking station or
not.
