Hi Sebastien,
my most recent attachment #11 is from a failed boot.
When it gets stuck, I get no keyboard response from Esc, ctrl-C. I don't think it is possible to log in to virtual terminals at this point in the boot, but if I try, I can get to a blank screen, which after a few seconds jumps back to the boot splash (stuck with the spinning ubuntu logo).
There is a burst of CPU fan soon after it gets into this phase, then it stops.
Also, it will suspend and resume quite well (of course, resuming back to the same screen).

I tried a linux kernel parameter to enable a systemd emergency console, but I could not access that either.
