  To: cpufreq

In a somewhat old computer I use at home, I have a Pentium 4 CPU running 
at 1.7GHz. On this computer, acpi-cpufreq does not work (modprobe fails 
with -ENODEV), only p4-clockmod. Lately this means I have to compile my 
own kernel to get speed throttling on my computer.

Recently, patch ed9cbcd40004904dbe61ccc16d6106a7de38c998 (Revert 
"speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1") 
broke clock speed reporting. It now reports I have a max speed of 13.80 
GHz instead of 1.7GHz. I only wish my CPU were that fast... Reverting 
this patch fixes the problem for me. However, since I suscribed 
yesterday to this list, I see talk about removing p4-clockmod altogether 
from the tree. Maybe my real problem is that acpi-cpufreq does not work 
even though it should, but I have yet to find a way to make the module 
print the information that is supposed to be displayed through dprintk() 
messages. What else can I do to debug acpi-cpufreq on my machine?

perl -e '$x=2.4;print sprintf("%.0f + %.0f = %.0f\n",$x,$x,$x+$x);'
