Summary0016314: Peculiar warning during boot and in log-messages
DescriptionWhen I boot the machine I get the warning: AMD Processor - this hardware has not undergone upstream testing. Please consult http://wiki.centos.org/FAQ for more information.

I use CentOS 7 since it was realeased in 2014 on this very machine and up to now got no such warning. This issue exists
since I've updated the kernel form version 3.10.0-957.21.3 to version 3.10.0-957.27.2. The CPU is an AMD Phenom II.

The logs show this:

During the update to kernel 3.10.0-957.27.2 there were many commits related to AMD CPU, you can check those here https://git.centos.org/rpms/kernel/c/2805d88868622f5422be63bcc479fe444543570d?branch=c7
This seems to be related to those changes.
