[MT-AU Public] Omnitik Half Duplex Issue

Hi guys, a while back I asked the list about the issues we seem to have with Omnitik 5Hnd units and them randomly syncing up in half-duplex 10M, I have exhausted all options with these and after just having yet another one do it I am at my wits end. It doesn't seem to matter whether you use auto-negotiate or try and hard set the interface speed on the device itself or the device that plus into it but they just randomly decide to go to 10M half-duplex, has anybody else seen this and come up with a concrete fix by any chance ? It only happens on Omnitiks and it seems that it's only on the ether1 port from what I can see. Regards Paul
