HP zbook studio g3

i7-6820hq, nvidia quadro m1000m

I'm booting with: iwlwifi.d0i3_disable=0 iwlwifi.uapsd_disable=0 iwlwifi.power_save=1 snd_hda_intel.power_save=1 e1000e.SmartPowerDownEnable=1 pcie_aspm=force pcie_aspm.policy=powersupersave

* Having ethernet plugged in (e1000e) makes it only get to pc2

* Having the discrete gpu powered off with bbswitch while xorg starts freezes the machine

* Having the discrete bpu powered off with bbswitch while loading the proprietary nvidia driver freezes the machine

* nouveau seems to freeze the machine no matter what bbswitch state

* Using bbswitch to power off the gpu it only gets pc3, loading the proprietary nvidia driver instead causes it to get into a lower pc-state (pc8? iirc), but more total power usage

* switching the powertop tunable "Runtime PM for PCI Device NVIDIA Corporation GM107GLM [Quadro M1000M]" makes the nvidia driver fail to load until next reboot (even if you switch it back)
