6.0-REL && CPU M770 (cold) M740 (hot)

Tue Jan 10 01:36:11 PST 2006

Hello,

In the past two weeks I've installed the same 6.0-REL configuration on
two Fujitsu-Siemens notebooks:

Amilo Lifebook E8020 with Intel M770 CPU (2.13 GHz)
Amilo M 1437G        with Intel M740 CPU (1.73 GHz)

the one with the M770 runs very cold and nearly never the fan comes
up even when KDE is running the fan does not switch on, while the M740
runs very warm with fan nearly always on, even if KDE is not launched;

as well there are a lot of differences in the sysctl's output
of both systems; I'm attaching of bot the 'sysctl -a | fgrep acpi_'
because it seems that it has to do with the problem; I did not load
any kernel modules related to CPU usage, for example the kldstat of
the M770 looks like this:

Id Refs Address    Size     Name
 1   14 0xc0400000 63070c   kernel
 2    1 0xc0a31000 4d08     if_tap.ko
 3    1 0xc0a36000 57c8     snd_ich.ko
 4    2 0xc0a3c000 1d408    sound.ko
 5    1 0xc0a5a000 a30c     if_iwi.ko
 6   16 0xc0a65000 568dc    acpi.ko
 7    1 0xc27ad000 2a000    ipl.ko
 8    1 0xc28e4000 15000    linux.ko

What is the problem with the one with the Intel M740 CPU?
Thx in advance
