Comment 5 for bug 774916

Yeah, I meant cores when I said cpus. Anyway your cpuinfo_max_freq = cpuinfo_min_freq as I expected. The applet kinda assumes that cpuinfo_max_freq > cpuinfo_min_freq. Don't know why they're the same on your system. Can you do:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

And for the fun (I don't have access to a multi core machine running Linux):

cat /sys/devices/system/cpu/cpu0/cpufreq/related_cpus
cat /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus

Please also do:

uname -r

And:

dmesg | grep centrino

and:

dmesg | grep cpufreq

Btw, have you tried to do cpufreq scaling before (working)?
