Not sure if that is helpful, but I get a similar issue with GTX 1050 Ti (GP107M), that's the dGPU in a Thinkpad X1 Extreme laptop. There's a setting in laptop BIOS to switch between hybrid graphics and discrete. When running in "discrete" setting, the system actually works and I'm able to use both console and X11 with modesetting DDX and nouveau driver. I get a similar timeout as the one reported here, see full dmesg and lspci attached. In "hybrid" mode, I can boot into console but overall things look less promising - lspci hangs and so does X when started (could very well be my mistake). Tested with kernel 4.20.
Created attachment 280325 [details] dmesg from thinkpad x1 extreme / GTX 1050 Ti on kernel 4.20
Created attachment 280327 [details] lspci from thinkpad x1 extreme / GTX 1050 Ti on kernel 4.20
Retested with latest 8.1 build from Redhat on a thinkpad X1E same configuration as the second user on this ticket and unable to reproduce this issue using kernel 4.0.18-91.el8
Created attachment 282927 [details] dmesg from thinkpad x1 extreme / GTX 1050 Ti on kernel 5.1.4
Retested on Thinkpad X1E with kernel 5.1.4-arch1-1, "discrete only" mode in BIOS and got the same timeout - see full dmesg for details.
