Re: 2.6.17 -> 2.6.18 regression: cpufreq broken since 2.6.18-rc1on pentium4

Do I understand your logs right and acpi-cpufreq is already loaded and works on your processor?
Do you have any info in /sys/devices/system/cpu/cpu0/cpufreq ?
Why do you want to load p4-clockmod over it? It does not save you any power, just limits performance.

I have similar problem with cpufreq-nforce2 --
I haven't do a git-bisect yet.

To recap, cpufreq died for at least two people (Tomasz Torcz and me) between
2.6.17 and 2.6.18-rc1. I've cc'd everybody who touched cpufreq according to
the shortlog.

Abundant details are in:

New information is that I've narrowed it down from between and
2.6.18-rc1 to between (which works) and 2.6.18-rc1 (which doesn't).

The problem exists both with cpufreq as modules and staticly, and both with
P4 and nforce2.

Please let me know how I can help you solve this problem. I'll try a git
bisect but a lot of the cpufreq changes appear to be interrelated, so I'm
unsure if it will work.
