[Bug 475706] Re: ondemand cpufreq governor broken on core 2 duo cpu

[uboot]

Gerhard, yes - it is definitely related to temperature.

At 85C the cpu throttles by 50% to 1.2GHz until it is cooled down below
50C I guess. At this point, I cannot select higher frequencies via
cpufreq-set. I reports a maximum selectable frequency of 1.2GHz. When it
is cooled down, it reports 2.4GHz max and I can set 2.4GHz again.

And I even managed to reach 95C, where it throttles to 400MHz

With Windows XP x64 it is the same.

I re-applied thermal grease and "optimized" airflow by moving a cable
inside the casing and now it is better.
