I'm confirming that CPU scaling still does not work in Edgy with either the 686 or 386 images. I'm running an Inspiron 8600 Petium M 2.0 GHz. Both max_frep_scaling and min_freq_scaling are stuck at 600 MHz. Trying to set this manually via:
sudo cat cpuinfo_max_freq > scaling_max_freq
results in:
bash: scaling_max_freq: Permission denied
even though scaling_max_freq is writable by root. As suggested, I also tried:
and this also results in a "Permission denied" error. I've been having issues compiling the kernel so I haven't tried the patch that was posted above yet, but I'll try to do so later in the week.
