There are indeed still issues. My Yoga 900 is also based on Skylake. It doesn't get into deeper package sleep states than pc2. Was on the internets a few days ago. I think the kernel guys will appreciate you reporting the bugs. I will at least. :-)

you need to install the firmware from intel www.i0.org, I did that and at least my sleeping problems reduced
