So your serial console works for userspace, but is broken from the
kernel? That last "Resetting..." is from the OBP I think.

That "Booting Linux..." is from the kernel too, but it's a prom_printf,
not a console (iow, sunsab) call.

And then userspace is ok again.

Dave, what's the difference between userspace going through the tty, and
kernel printk calls going into the console callbacks?
