Title:
Using an NVMe drive causes huge power drain
Status in linux package in Ubuntu:
Triaged
Bug description:
PCIe NVMe drives are very common in new laptops. 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.
