I'm almost sure that it will not help because with default selinux=1
boot is stuck still in initrd.
Just checked dmesg:

Above it is still from dmesg messages of the first boot in which
initial-setup has been started.

Theoretically selinux=1 should not be affecting fb initialization but
knowing that that I had SELinux issue on NanoPi Neo2 at some point
I've prepared fresh RPi3 sd card with added selinux=0 in grub2.cfg
file and whole boot passed this critical point.
Maybe next step afer display this message is affected by selinux=1?

Will try confirm above tomorrow (now I must finish some new base setup
of some POC on this RPi3).
