I do the same although I use vt102 - shouldn't matter.

Here I am a little more specific although the extra bits may be the
default anyway. I use

serial --unit=0 --speed=9600 --word=8 --parity=no

What boot information are you talking about here? The BIOS boot
information? That would be something you may need to set in the BIOS I
believe. The bits we are doing here don't come into play until after
some of that is finished.

Here I use

console=tty0 console=ttyS0,9600n8

although the order and which tty I guess is whatever is most
appropriate for your situation.

Can you figure out which module it is complaining about? Anything in
the messages or boot log files? If the systems are otherwise the same,
as far as you know, perhaps lsmod on one that complains and one that
doesn't might shed some light on it?!
