Fortiswitch 7.6.6 802.1x Broken?

I am setting up 802.1x with clearpass and most of my switch are running 7.6.1 or lower and are working fine. I upgraded 2 switches this morning to 7.6.6 and now they absolutely refuse to work if I have the 802.1x security policy on the ports. Worked fine on 7.6.1. Not even DHCP is getting passed to the native vlan.

I've spend the majority of my day trying to find a way to work around this today and am at the end of my chain.

I can't even roll back to 7.6.1 because I don't have switch support to download.

I ran a sniffer on the fortigate and the switch doesn't send a single RADIUS packet when a port comes up.

Anyone have any suggestions?
