"Hello. It's me" again

I found next bug.
Problem on boot.
Boot stop when init print version.
The screen becomes green :P

My card: MSI GeForce GT 720

This is common problem on some graphics cards

It's problem with Legacy Framebuffer drivers (in kernel).
I had that same on my Gentoo system
All what you must know is here: https://wiki.gentoo.org/wiki/Xorg/Guide#Kernel_modesetting
(Yes it's from Xorg Guide but it repairs problem)

PS. Thierry you should setup a bug tracker  ;)

Can you add the option nomodeset to the kernel line: means you should have some think like this after modification:
linux /boot/kernel root=/dev/sdaX ro nomodeset quiet
initrd /boot/initrd


Another possibility is probably to blacklist the module which trouble you:

echo "blacklist vga16fb
blacklist ocfb
blacklist udlfb
blacklist udlfb
blacklist vfb
blacklist hyperv-fb
blacklist vga16fb
blackkist uvesafb
blacklist viafb
blacklist sstfb
blacklist i810fb
blacklist hyperv-fb" > /etc/modprobe.d/fb.conf


You find all the fb modules in

find /lib/modules/4.4.6-NuTyX-lts/kernel/drivers/video/fbdev/
