ADV 7511 socket disconnect/cable gone messages

We have 2 different hardware platforms using the ADV7511 HDMI TX device. We are not using HDCP.

Essentially on both platforms the HDMI out is working fine almost all of the time, but every few minutes/hours the ADV7511 driver reports either

Serial:

Detected interface type: HDMI
connector_status_disconnected
connector_status_connected
(....other stuff)

 

Serial:

Detected interface type: HDMI
Cable gone
Cable detected
connector_status_connected

(....other stuff)

 

At the same time the monitor flashes and recovers again immediately. We use 1080 P59.94 mostly, but it happens on other video standards too. 

For control we are using the standard linux driver on an ARM processor running linux.

 

Any ideas ? We have connected a Quantum Data 380 HDMI analyzer  but this reports nothing untoward is happening.

 

Thanks

Tony
