Could you point me to some more info about this (I couldn't find any
bug reports)? I'm interested in following up on it so we can one day
move to ondemand by default. For what it's worth, fedora and opensuse
have been using ondemand for some time. Is it known why we are seeing
problems and they are not?

My understanding was that ondemand is recommended by upstream
(http://www.codon.org.uk/~mjg59/power/good_practices.html), and that
it should automatically fall back to performance if the HW latencies
are too high. Please correct me if I'm wrong.
