It is likely that newer versions of /etc/init.d/ondemand script were never backported to the older 12.04 precise release. Why not? Well, because, as far as I know, that release never used the intel_pstate driver by default and so never had to fall through to the powersave alternative. Earlier on this thread, Srinivas correctly asked Jörg what distribution was being used, so as to hopefully make it easier to reproduce the issue. If we want to continue this distro specific conversation, perhaps we should move it off-list or to some Ubuntu specific forum. ...
