so you have two consoles: ttyS0 and tty0?
and I see "bootconsole [earlyser0] enabled" but no "bootconsole [earlyser0] disabled" message, which
I'd expect to see...
So how may consoles do you have? 2 or 3? so call_console_drivers() has to ->write()
every log line N times; at least to ttyS0->write() and to tty0->write()?
