Where does the map come from, is it network based?
If it is and you use NetworkManager, have you checked to see if
automount is starting up during NetworkManager initialization?
In the log you show why do we see automount shutting down, then starting
up, you say the problem is at boot but the example log doesn't show an
error at boot?
And, did you check if /home was already mounted after the shutdown and
before that startup in the log.
