Previous Auth invalid

I have a setup, with around 40 R510 running FW 6.1.1.0.1274, SSID with WPA2 PSK, located at a customer.
We have had no issues with clients connecting to the SSID. This SSID is a semi open net that functions as a guest net, so I have all kinds of clients connecting to it, with no issues.
The customer have now bought some smartscreens from I3 technologies model is E-One86.
These screens are a nighmare, some will connect and work fine, some will connect and just be thrown off again within 5 min, and some will not connect at all.
I have alot of these faults from them.
"EAPOL Failure: Previous Auth invalid"
When I look at the fault, it looks like the AP sends Frame-1 in the 4-Way Handshake a few times without any response, so in the end the AP sends a Deauth packet.

This is not something I have seen before, and must admit I'm abit lost here.

Anybody have any experience with these screens or this fault ??

Curious, Tommy, did you get to know what the cause for this info was? I am getting lots of packet losses from phone clients especially A04E and upon troubleshooting, I get this Deauthentication
