[Solved] Lost Network Adapter after upgrading to 21.1.6

[s4rs]

I have a Supermicro system with quad Intel I354 adapters. I upgraded to 21.1.6 last night and now the adapters are dead. I use a single vlan'd adapter our of the four (igb0). It is seen in pciconf but shows no carrier in ifconfig. Any suggestions?

Cable and switch ports are good.

Turns out this was a HW issue. Even though I did a power off/on I had to remove power from the system then power it on to resolve the issue. This wasn't an upgrade issue after all.
