I have a 3 node cluster running Minisforum MS-01 hosts, using Thunderbolt as the intra-cluster networking for Ceph. Everything was configured and working smoothly prior to recently upgrading to PVE 8.4, and kernel 6.8. I'm not exactly sure which one caused the issue, but I noticed some strange behavior on 1 of the 3 nodes. Specifically, after a reboot, the networking does not start up properly, leaving the host off the network. After logging into the host directly, I can see that networking.service did not start successfully. I checked to see if the `networking` service is enabled, which it is. Restarting networking.service does resolve the issue and brings the host back online, but this has to be done manually each reboot. I compared the configuration between the hosts but I don't see anything that differs for this particular one. Looking for some guidance on what I'm missing here.
