Everything is now clear to me.
I was doing rsync with -x when copying data - so /dev nodes was not
copied because /dev was mounted as tmpfs - so as a result i have
empty /dev directory on /dev/md0 (boot partition).
Unfortunately INIT doesn't warn if i.e. /dev/console is missing :(
Please consider put a warning if essential and critical /dev/ nodes
are missing.
