Public bug reported: 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: zesty -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1664602 Title: Using an NVMe drive causes huge power drain Status in linux package in Ubuntu: New Bug description: PCIe NVMe drives are very common in new laptops.
