When resuming from S3 suspend, serial console starts sending garbage
on the serial port.
Not continuously, it sends garbage only when in local console prints a
text.
It stops only when the (sending) machine is shut down, or if some
text is sent manually (i.e. with "cat txtfile > /dev/ttyS0").

Full details are here:

The problem is still present in final 3.14 (and in linux-next).
