Re: "processor" acpi module permanently throttles processor

I've googled for generic options in kernel configura-
tion. Then asked old friend for his suse conf file.
Both are the same. Have acpi enabled, acpi_processor
enabled, also cpu_freq. That post to mean that the
system is saving the power.
Laptops have to last longer, so the consumption should
be deplated. Processor frequency goes down, in this
case. My celeron of 1400 runs at lazy 174. Cool as breeze.

Some thing could be done. Try out with
"sysctl -a". Find apropriate option and
read manual on it.
If fails, you could always recompile the
kernel. To remove tons of superfluous op-
tions (aka drivers). Lapper will breath
again, hopefuly.
