Does journalctl -b show anything interesting when you run it in the rescue shell?
I don't know what data from journalctl -b is interesting for this. One thing I found that could be related was that rngd.service always failed to start. Fortunately, this problem stoped happening after a system update wich included Kernel 3.14 among other packages.
OK, closing if the problem vanished.
