>Description:

I have a notebook on which cpu-cooling is failing

When running big jobs (or just a simple buildkernel) it will
auto power-off since too hot unless I stop cpufreq and fix frequency to
some intermediate value

I would be nice to have some sysctl debug.cpufreq.highest to tell it not to
go higher than a certain freqlevel (as possible with the old acpi_ppc.ko
hw.acpi.cpu.px_highest control)
>How-To-Repeat:

>Fix:
Use acpi_ppc.ko instead (corrected source for some changed ACPI names)
