I have an i7 8750H with a GTX 1050 Mobile. I applied these two patches on top of Linus' tree. After I switched all "power/control" to "auto", everything works now. Card powers down, suspend/resume works.

Thank you for figuring this out. Before this I was getting lockups with bbswitch/acpi_call during boot. I had to do crazy workarounds to get away with this during early boot and suspend/resume. Those days are gone now!
