I append drm.debug=0x3 to boot command.  Whenever, the screen flashes,
I notice the logs like this:

I should explain this in more detail.  Here are the steps to reproduce
this issue:
1. Before unplug the HDMI cable from HDMI0 port.
$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 2048 x 2048
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x
axis y axis) 521mm x 293mm

2. Unplug the HDMI cable from HDMI0 port.
3. Plug the HDMI cable to **HDMI1** port.

4. Unplug the HDMI cable from **HDMI1** port.
