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 :

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.
