And obviously without providing the log thereof (with "loglvl=all" in
place) there's quite likely no way we can find out what's going
wrong. If you have trouble setting up the serial console, yet the
system is coming up fine (which it looks like it is), "xl dmesg" right
after boot completed will do as good a job in obtaining the log.
