Also tested Kernel 4.4 RC8 => the same error appears in /var/log/syslog when i connect my laptop to the tv with a hdmi cable. The error appears only at the moment when i plug the hdmi cable. Then it stops. Then i change the configuration of the sound to hdmi display port. And the same error occurs at the moment i changed the sound configuration. see dmesg in attachment.
