The Zesty's kernels (including latest 4.10 rc8 from CKT PPA) does not support APST (autonomous power state transitions). A patch does exist : http://lists.infradead.org/pipermail/linux-nvme/2017-February/008051.html https://github.com/damige/linux-nvme It seems that we cannot expect this before kernel 4.11. Additionally my laptop CPU does never go under PC3 power saving state, powertop says. I don't know if it's related. --- ApportVersion: 2.20.4-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ft 1900 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 17.04 HibernationDevice: RESUME=UUID=a04b55bf-b1b6-464c-88ce-44b6adbbbc10 InstallationDate: Installed on 2016-12-12 (63 days ago) InstallationMedia: Ubuntu-GNOME 17.04 "Zesty Zapus" - Alpha amd64 (20161211) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub MachineType: Dell Inc.
