--- Comment #1 from Barry G <barry at grussling.com> ---
Last night I updated the kernel to

1086abf3e8ab8eaf7355c6362bad28283b4fb021 (drm/amd/display: USB-C / thunderbolt
dock specific workaround)

from https://cgit.freedesktop.org/~hwentland/linux/commit/?h=4.15-rc1-fixes

per the amd-gfx pull request.  It did not affect this bug.  It took 4 boots for
my displays to come up with content on 1086abf.

Also note this particular system doesn't have a reset button, owing to the fact
case manufacturers appear to be removing them.  As such, these are all cold
boots.  I could wire up a hacky reset button if warm-reset behavior would be
helpful.
