That doesn't mean it isn't working, though.
I didn't say that cpufreq ondemand is broken. It's a hardware problem.
I here weird noises if the cpu
is clocked anywhere from 333MHz to 1GHz (sounds like an RD-D2 beeping
noises in ultra high pitch?)
Yes, something like that.
Is it actually "not working" though, even at the hardware level? To my
knowledge those noises are normal, and aren't even signs of a harware
problem. I believe it is the natural result of changing frequencies at any
time. If you change frequencies, especially in the low end of available
frequencies, you should hear a very brief noise. A governor such as
ondemand, which is rapidly switching the frequency from say, 333 MHz to
2.66 GHz, is likely to make this much more noticable.
