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

While serial console seems to work:
1) I keep seeing boot log messages after:
[    0.402309] 18000300.serial: ttyS0 at MMIO 0x18000300 (irq = 18, base_baud = 6250000) is a 16550
2) Typed chars come back to my serial console

I can't log in. I press ENTER but I'm not getting prompt for entering user name.

Do you know why this change could have such an effect?
