"Hardware changes detected ..." error when restarting OS

I will post for the first time.

Although the hardware (NIC: Label3) was not changed, an error message was output after the AMD server was restarted and data collection stopped. As a result, Label1 and Label2 data can no longer be collected. The hardware of Label1 and Label2 has not changed.


I want to know the following.

1. Why Label3 hardware recognition changed after AMD server restart

2. Why Label1 and Label2 can no longer collect data


-----------------------------

cmd: rtminst

Network setup:

Default gateway: xx.xx.xx.xx

Hostname: AAAAA

AMD type: Probe HS

Driver type: native

Did you recently update your RHEL/CentOS? There is a known issue with one of the updates that reshuffles how the networking hardware is identified.
