I was copy pasting about 1k of text into terminal to Linux operating over serial console (didn't setup ssh server and port mapping yet), and well, kernel said this:
[ 269.280000] ttyPZ0: pmz: rx irq flood !
after this, the terminal / serial console is not usable.
At least I can't sand anything again.
I guess it would make sense to throttle rx irqs on serial lines to be in some sane range? Try to emulate some baudrate limits that the driver expects to be sane too?
