Latest kernel is in testing, - fixed archiso support - revert to performance governor
Looked in the tracker and didn't see anything. Just curious, why are we reverting back to the performance governor?
There might be trouble, as the ondemand governor does not work with all CPUs.
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. Cheers, Tom
