Could you paste the output of sudo lspci -vvv and cat /sys/devices/virtual/dmi/id/bios_version somewhere?

Not OP, but I have dell xps 15 skylake. (i3-6100H)

I am currently running Ubuntu 16.04 4.4.0-8 kernel which works fine. The ubuntu backport of i915 from 4.6 to 4.4 which is present in 4.4.0-9 causes weird video issues. (upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=94593)

Only the ultra-low-power chips (U and Y series) are susceptible to damage from poor power management.

any source?

Sure!

lspci -vvv: http://pastebin.com/raw/FUsMqPZz

cat /sys/devices/virtual/dmi/id/bios_version: 1.2.3

Happy to provide any other info as well, I love this machine to bits and would be happy if I could help other people enjoy it too.

Could you re-run the lspci as root? Thanks!

This is probably a slightly different configuration, but I also see support for low Cstates on my Skylake processor (running 4.6.0 rc2)
