I'm really sorry for making all the noise! Forget about the stuff I sent
before.
I applied the patch Marco pointed me to, and then yours, Colin. They
applied fine and the kernel compiled well.
When the computer booted the fan startet (therm_adt7467 not loaded) When
I did modprobe therm_adt7467 the fan stopped. After a whilei the fan
starts:
cpu_limit: 50�C
cpu_temperature: 49�C
fan_speed: 82
cpu_limit: 50�C
cpu_temperature: 49�C
fan_speed: 8585
After cooling under 47 centigrade, the fan switches off again. But if I
try to create higher cpu-load using something like
while (true); do for i in cpu_limit cpu_temperature fan_speed; do cat $i; echo; done; done
the machine switches off when cpu_temperature reaches 56 centigrades.
The first time this happened, I got the impression that shortly before
the machine switched off the fan powered up even more. But this was not
the case when I followed the output later over an ssh-connection.
The shutdown does not happen if the module is not loaded.
Yours sincerely,
Wolfi
