[CentOS] CentOS-6.8 PCI Hwdr issue?

Wed Sep 21 21:00:05 UTC 2016

I have begun to see these messages in my morning reports:

The system is the KVM host for a number of our virtual guest servers. 
Investigating this further has revealed that these messages being
produced in vast numbers and that the messages log file is bloated in
consequence.

These messages are generated ceaselessly.

Research reveals that this error is possibly related to some sort of
driver incompatibility involving Realtek chip sets.

However, I do not seem to have this hardware installed on this host:

Can anyone shed any light on this problem?  The system in question has
been running some years and is only lacking the most recent updates.
