Got a nice update on ticket, my unit will be replaced.
For thoses who still wait a reply, don't worry they will answer it.

Someone had an update on this issue (Ticket or something) ?

@fossette That was what I got using the serial console on boot

Here all the boot sequence :

   ____       _             ____ 
 / __ \___  (_)__  ___    / __ \__ _  ___ ___ ____ _ 
/ /_/ / _ \/ / _ \/ _ \  / /_/ /  ' \/ -_) _ `/ _ `/ 
\____/_//_/_/\___/_//_/  \____/_/_/_/\__/\_, /\_,_/ 
W H A T  W I L L  Y O U  I N V E N T ? /___/"
