Ok, it was a long shot anyway.

Can you tell me which test equipment are you using?

Hmmm, my first thought was that audio is being configured first because of the phy lock wait time, I've seen this happening before.
Lets try this: - Disable all alsa clients (e.g. pulseaudio, ...) so that no one tries to configure audio. - Plug out/in the cable until the issue appears - When the issue appears use aplay to play audio through the HDMI output - Repeat several times with different audio rates and with no resample (you can use the plughw interface in aplay).
