CPUFREQ -- how to disable?

[chazbroam]

I have this old Dell Latitude that I am working on for my mom. The only real glitch it has is: it does not allow the software to handle CPU scaling. So anything with CPUFREQ, it just does not compute due to a firmware bug on it. It has only one CPU -- a Celeron 2.4 GHz. It is only single core -- 32bit.

I don't even want "Userspace" to run. Really. I want to turn the the whole thing OFF. So how do I go about it? I've tried to turn it off in /etc/rc.d/rc.modules, but that doesn't work. After a reboot, it's right back on.

pass the intel_pstate=disable to the kernel at boot. e.g. in your lilo.conf file
Edit:

Code: Select all

append="vt.default_utf8=1 intel_pstate=disable'

[chazbroam]

Code: Select all

append="vt.default_utf8=0,intel_pstate=disable'

It worked for one reboot, then went back to reporting 12MHz CPU speed (Conky).

Next suggestion please?

edit /etc/rc.d/rc.modules
on line 886, #/sbin/modprobe cpufreq_performance remove the # from the beginning of line
or at
line 823, line 830 CPUFREQ=on ( turn it to off)
and bellow
Play with this file settings to disable it.

Hello djemos,

I would like to make a correction. In the append= string, the comma must be replaced by a space. Commas have different meaning.

If originally vt.default_utf8=1 was present, and now vt.default_utf8=0 is valid, then it might be necessary to run unicode_start.

it was just an example. User can have whatever he likes in append=""
intel_pstate=disable is the needed parameter. As for the space, yes you're right.
