Description:
Linux kernel 686 can't scale cpu frequency. I have tested it on two machines one P4 ULV and a standard P4 M with 1.8 ghz and both times it doesn't work. All modules are loaded and it shows under sys the correct min and max value but you can't change it and powernowd too.
With 386 scaling works fine.
