Description of problem:
I have a 1666GHZ processor on the Sony VAIO PCG-FR130 laptop. On a
different harddrive I have installed RH Linux ES and when I go to
/proc then cat cpuinfo, I am able to view the appropriate value for
the cpu (MHZ) field of 1666. I recently bought a new harddrive and
installed Fedora Core 2, which seems to run perfectly, however when I
do a cat /proc/cpuinfo I get the value of 400.243 which is
significantly lower than the installed processor.

I am thinking this a kernel problem as the /proc files are calculated
during initialization.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
2.cat /proc/cpuinfo

Actual Results:  false value for cpu (MHZ) which is 400

Expected Results:  value should be 1666

your laptop has a speed scaling capable processor, which saves battery life.
If you dislike this feature, you can disable it with
chkconfig --level 012345 cpuspeed off
