Black screen after login with wayland, GTX750i, through DisplayPort to a Dell P2715Q under fedora 27: unable to handle kernel NULL pointer dereference at 00000000000000c0

My screen goes black after login (assuming when wayland starts) with fedora 27 on a GTX750i. Am including my dmegs and ndivia-debugdump output.

I do see these errors in dmesg output. All the details in the attached files;
