Happy new year
I was thinking that the problem was related with specific hardware/components... but as I see here and on Internet, it isn't.
I saw a few posts where people got this problem five years ago (ubuntu 12.04) !
For some of them, disabling WOL resolved the problem.
I saw other posts which recommends to add something into grub config file... or new systemd services or scripts...
I tried most of them, none works.
