I spent all the night on it, I've tried mkinicpio, check (ldd
/sbin/init), if executable, downgrade the kernel... Without success,
so I've reinstall everything and now it is working.

This failure is a complete mystery for me, it is the second time it
happens , finally I decide to ban the command "pacman -Syu" :-(

thank you for your help
