Bug Description
Binary package hint: ntp
The current design of ntp makes it generate at least 1 wakeup/second, thus disallowing the CPU to enter deeper states of sleep [1].
I propose applying a patch from Fedora which solves this issue. Previous attempts at integrating it upstream failed [2], despite the fact that the patch is used in Fedora for a long time. Hopefully, with the increasing need for energy efficient computing and Ubuntu validating the approach, upstream will be more willing to integrate the fix.
I attach the patch which has to be copied to debian/patches and added to debian/series.

Thanks for reporting this bug and helping to make Ubuntu better.
I'm not sure how others will feel about it, but it sounds like a good idea. However, we should try and get this applied through the upstream Debian package if possible. Please let us know if this is something you're willing to try yourself, or if you prefer us (me) to forward it.
