Thanks for getting back - I followed your instructions. It seemed I
needed to swap console=ttyS0 and console=tty0 BUT opposite from what you
suggested. That is, console=ttyS0 was last and by swapping it with
console=tty0 and making console=ttyS0 listed first I had rc script
(userspace) messages reported to ttyS0... Strange?
Stranger still, when I did the above, I stopped getting a login prompt
on ttyS0. So, swapping as I said above (opposite to your suggestion)
gave me rc script messages to ttyS0 and no login...
Do you have any ideas how to get the login prompt back?
It is a bug in plymouth (which provides the graphical boot animations).
You can add "rd_NO_PLYMOUTH" to your boot line (as long as you don't
have encrypted filesystems) and the serial console should work as
expected (with console=ttyS0 listed after console=tty0).
I think it is fixed in newer plymouth, but I'm not sure. I see the bug
on RHEL 6 systems, and the fix has not been released there yet.
