[Kernel-packages] [Bug 1579917] Re: Skylake processor never reaches low power states on X1 Carbon gen 4 with NVMe drive

@djao, sorry for the slow response. I hit pc8 briefly, but that's with most everything tuned, and running nothing. Lots of applications seem to be pretty power hungry for me.

Skylake + sata appears to have a number of fixes in the 4.6 and newer kernels that enable some of the higher sleep states, but I have not tested with a sata drive. Those fixes as of testing 4.6-rc7 do not resolve this issue with users who have nvme drives.
