dmesg output

I have been unable to get a working TTY when using nouveau on my GTX 1060. I have been booting straight to TTY and the TTY flickers and blacks every few seconds. When my Ultrawide monitor is detected as the primary monitor, I also see colored artifacts on the screen. However, when I launch sway or a compositor, the flickering/artifacting mostly stops, but the compositor seems to be unstable.

I am testing with Arch Linux 64bit with Linux kernel 4.13.7, package version "1.0.15-2" for extra/xf86-video-nouveau which is current with Arch Linux extra at the moment.

I have attached the EDID information for both of my monitors obtained via /sys. I have also attached dmesg output from booting into nouveau and running into this issue.

Here is a link to the VBIOS that I have copied from /sys: https://xannode.com/vbios.rom
