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: https://bugzilla.kernel.org/show_bug.cgi?id=69751 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
