Since I have setup a new hardware - x570 chipset, rx570 GPU - I am
facing a very strange problem. The monitor goes blank for a brief time,
like 1-2s and then comes back. It is connected with the GPU using HDMI
cable.
During that 1-2s, the machine response is fine. Whatever I type during
that time goes there as input, and visible when the monitor comes back.
I don’t want to file any bug report till I have some concrete data. So
my question is - how do I diagnose such an issue and produce some data
for debugging. So that I can hand it over to maintainers.

You are not the only one. I see the exact same here. The system this
happens on has an RX560 graphics card. I have been seeing these
blackouts from the start on this configuration (more than 2 years now).
I can confirm it is not a mechanical issue (not of cable's connections,
cable defects, or of the seating of the card in the motherboard). It is
not the display either (I have tried multiple displays). I am almost
sure it is a software issue.
I can also confirm the system does not hang. I've tested this with a
software timer and a request/response loop querying a daemon both
locally and over a wired network.
