[Bug 22336] Re: laptop overheats when performing CPU intensive tasks.

[Nikolaus Filus]

@GreatBunzinni: Yes, it's possible. But that would be only a workaround for people suffering from the problem until a real fix is found and implemente.
Have a look at /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq. AFAIK this works only for kernel-space scaling and NOT if using powernowd and that alike. In this case there should be config option.

@all: 
fixed for me with: stop powernowd and use ondemand scaling

breaks for me: after resume from hibernation, sometimes thermal zone shows 0 and fan doesn't kick on. After short time cpu max throttling is enabled (by kernel?), what makes the system unusable because of reaction to events every ten seconds.
workaround: include thermal and fan in kernel, NOT module (tested before on gentoo, not verifed yet on ubuntu)
