Comment 5 for bug 67341

I have also seen this behaviour on our mailserver running Ubuntu 7.04 Server. I just commented out the following part of /etc/init.d/powernowd (lines 108-112):

if use_ondemand
then
  log_end_msg 0
  return 0
fi

Seems to work for me, powernowd is running according to ps and frequency scaling behaves as i wish.
