Hmm. I don't see anything wrong. Either as a pure serial console with no 
login (console=ttyS0,115400 console=tty0) or with the serial console 
actually being /dev/console and having a login on it etc.

But I have to admit to only using serial consoles for some very 
occasional debugging, so I might have missed any behavioral differences. 
It rebooted cleanly with no messages. But in this case "no messages" can 
obviously be both a good and a bad thing ;)
