Powerdevil fails, Energy settings unavailable

Going through the downgrade today and noticed that powerdevil-5.27.9-1 is not available on my system

5.27.9.r3021.gc299adfc located in remote and 5.27.9 in /var/cache/pacman/pkg

Where can I download 5.27.9.1? As Choosing 5.27.8 results in other issues :

Update: Rebooted fine & powerdevil is only consuming 1% of cpu time, the system stable and the network seems fine too. But Power management settings are still inaccessible. Thanks for all the help.
