Since older -nightly doesn't seem to be affected this sounds like a regression. Please bisect. Also please boot with drm.debug=0xe, reproduce the bug and reattach a new dmesg. You can leave out any other debug knobs, we don't need e.g. initcall debugging. Also please grab the output of xrandr before/after unplugging.
