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:

Monitors connected via DisplayPort:
Samsung U28E590D 28-Inch UHD LED-Lit Monitor
LG Ultrawide Monitor
