CPUFreq sysfs interface MIA? (since 2.5.69)
Quoted 3 lines
Under both 2.5.68 and 2.5.69 the CPUFreq /sys interface seems to be missing for my machine (IBM A31p), with an Intel 845 Brookdale chipset and SpeedStep support.
The same here, but it worked in 2.5.68. It's a P3 Speedstep. /proc/cpufreq only shows the header.
$ cat /sys/class/cpu/cpu0/device/name CPU 0 $ cat /sys/class/cpu/cpu0/device/power 0

Can you let me know if the patch I just posted to lkml in this thread fixes this for you?
thanks,

Yes, it does work.
