Using bootargs to pass the serial settings has been deprecated for a
while. Please use stdout-path instead.

I tried following patch with my SR400ac (I put Archer C5 aside for now).

Hi Rafael

Take a look at for example the bcm911360k.dts

       aliases {
               serial0 = &uart3;
       };

       chosen {
               stdout-path = "serial0:115200n8";
       };

You need an alias to the serial device you want to us, and you should
list the speed, parity, bits etc.

That was actually my first try (just with s/uart3/uart0) and I got the same
problem.

I have a similar line in the bcm953012k.dts, and the serial there works for me.

Well, the serial seems to work OK (I'm getting boot log & I can see my chars
being echoed back). I just can't log in. Can this kernel change somehow affect
user space?

Yes, it can. You probably don't have a getty running on ttyS0. But you
do have on /dev/console? Look in /etc/inittab.
