Description Massimo Burcheri 2005-06-26 13:59:13 UTC 
Eventhough the governor ondemand is on the list, I cant't enable it. 
Machine is a G3-600 iBook. 

Reproducible: Always
Steps to Reproduce:
1.# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
ondemand powersave userspace performance 
 
2.# echo "ondemand"> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 
 
3.# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 
powersave 
 
 
Actual Results:  
powersave and performance work. ondemand doesn't.
