As this issue only happens on cold boot, have you checked whether
there's an
updated BIOS for your system?
And does it really not boot or are you 'only' getting no display
output?
If the latter, can you ssh into your NUC and share `dmesg` output?
Hopefully
that'll give a clue as to why the DP/HDMI outputs aren't working
properly.
1. I have most recent BIOS (Aug '23).
2. That's a valid question :) It does boot after all, only display is
stuck. I was able to get dmesg -> attached.
I don't remember if I mentioned that, but 'nomodeset' kernel param does
not help..
