Hi, I just installed the patches available under http://www.kernel.org/pub/linux/kernel/people/kristen/patches/SATA/alpm/ on a vanilla 2.6.22-rc4 kernel and can see the respective sysfs entries which are set to "max_power". However, I can't change the value via echoing "med_power" or "min_power" - it stays at "max_performance". Is there anything else I have to do in the first place?
