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").

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

The problem is still present in 3.14.4, 3.15-rc7 and today's next.
I hope someone is going to look at this bug.
