dmesg from thinkpad x1 extreme / GTX 1050 Ti on kernel 4.20 with hybrid
graphics

I may be blind but I haven't seen anyone attaching full dmesg output, sorry if
I missed it.

The laptop in question is Thinkpad X1 Extreme with NVIDIA Corporation GP107M
[GeForce GTX 1050 Ti Mobile] (rev a1). It has a BIOS setting to switch between
"Hybrid" and "Discrete only" graphics. 

This dmesg output is from a boot with "Hybrid" graphics, where running 'lspci'
hangs and causes the system fans to spin. X server hangs on start too (using
modesetting DDX)
