After different testings, it appears that you were right, in the inittab file, both tty(1 and S0) are used.
So my problem looks more like a Kernel panic (I get a screen fuzzing just after the line Checking if you processor honors,etc…).
I tested the ALIX image but no more success (Error 13 of GRUB).
I don’t know what to do next and I feel a bit desperated :cry:. I don’t want to give up but I have no more clues to move forward.
I’d appreciate any advice.
