ESXi free edition – limit of physical NICs?

Is there a limit in ESXi (6.7u3) free for maximum physical NICs? I have a server that had two onboard GE ports and a dual port GE addin card. Both show up and were usable in the ESX networking stack.

I needed a couple more physical ports so I added another new dual port 1GBE network card. (all are Intels on the HCL)

However when I rebooted ESXI after installing the new card, the onboard ports and the NEW ports show up as vmnic0-1,4-5 but the original addin card no longer shows as usable vmnics.

Before I had:

vmnic0
vmnic1
vmnic2
vmnic3

​

Now I have:

vmnic0
vmnic1
vmnic4 (new card)
vmnic5 (new card)

​

The card that’s missing still shows up in the BIOS and POSTS… also shows up in UCS IMC inventory, so it’s still there…

The only thing I see now when ESX kernel boots are these two messages:

2020-09-03T14:41:59.887Z cpu15:2097686)PCI: 1254: 0000:18:00.0 named ‘vmnic2’ (was ”)

​

Ideas?
