--- Comment #5 from Robert N <crshman at gmail.com> ---
I'm not entirely sure if this is a regression. I just got this hardware and
this is my first time trying this setup on linux.

I can try a few older kernels to see if I can find something, but don't feel
overly confident.

I've attached an updated copy of the dmesg output.

I bring up the display manager and reconfigure my second monitor from "off" to
"secondary" at:
[  167.615280] [drm:drm_mode_getconnector] [CONNECTOR:37:?]

I let if flicker for a bit and then disabled the second monitor back to "off"
at:

[  203.763410] [drm:drm_mode_setcrtc] [CRTC:21]
