Hi all,
I just switched from Fedora Linux to FreeBSD. But I noticed a problem,
the CPU temperature will be very high when the load is high. Especially
while I am building C++ programs. It shut down for even 3 times while I
was building Firefox/Thunderbird, just because of high temperature (86.5C).
One of my friends told me, "FreeBSD doesn't support your ACPI well" but
I noticed that while I'm not compiling ports, the temperature will be
not too high.
Just now I'm building LLVM, here's what I've seen:
> sysctl hw.acpi.thermal.tz0.temperature
hw.acpi.thermal.tz0.temperature: 84.5C
> pkill make
> sysctl hw.acpi.thermal.tz0.temperature
hw.acpi.thermal.tz0.temperature: 67.5C
I'm using Dell Vostro 3400 laptop PC with FreeBSD 9.1-RC1.

There's my dmesg message: http://slexy.org/view/s21b7xTTsu
Anyone knows how to fix this problem? Thank you.
Yours Sincerely,
Mike Manilone
