FC5, core duo T2600, cpufreq works just for cpu0


Just installed FC5 on Intel core duo T2600 system (MSI 945GT Speedster motherboard).
Frequency scaling worked out of the box (cpuspped - style), but just for cpu0 (core 0). The other core (cpu1) runs all the time on the max clock frequency (2.16GHz), even with minimal system load.
Then stopped cpuspeed, tried ondemand:
service cpuspeed stop
modprobe cpufreq_ondemand
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

with the same result - CPU freq scaling works just for cpu0.
Last command gave "No such file or directory" error, so
I found out, that /sys/devices/system/cpu/cpu1/cpufreq does not exist!


ls /sys/devices/system/cpu/cpu0/
cache cpufreq crash_notes topology

ls /sys/devices/system/cpu/cpu1/
cache crash_notes online topology


Any idea how to make this work?
Is it udev/sysfs issue?

Problem solved by flashing motherboard BIOS.

MSI 945GT Speedster comes with 1.0bC BIOS version, which is probably beta.
Flashing to real 1.0 downloaded from MSI support site fixed the speedstep problem.

Which cpufreq driver do you use? I can't get cpufreq work with my Core 2 Duo E6300.

P.S. Solved by using speedstep-centrino driver
