Description Stephen Hemminger 2006-11-24 18:56:57 UTC
Description of problem:
Since the cpu frequency control for Pentium-M is not enabled by default
in the FC6 kernel (CONFIG_X86_SPEEDSTEP_CENTRINO). There is no frequency
control and laptop always runs full speed.

Version-Release number of selected component (if applicable):
2.6.18-1.2849.fc6

How reproducible:
100%

Steps to Reproduce:
1. boot
2. look for cpufreq in /sys (it's missing)
3. frequency control from gnome-power-manager etc can't work

It works if I build a upstream kernel and enable it.  

Actual results:


Expected results:


Additional info:
Is this intentional or unintentional

Hrmm.

$ grep SPEEDSTEP /boot/config-2.6.18-1.2849.fc6 
CONFIG_X86_SPEEDSTEP_CENTRINO=y

Oh, I bet I know what this is.  I bet you've been bitten by the "installer
installs a 586 kernel by default" bug.  
See http://fedoraproject.org/wiki/Bugs/FC6Common  and see if that's the problem.

If that still doesn't get you up and running, attach dmesg, and I'll poke at it
some more.
