The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes a specific CPU / processor error message observed with Cisco Unified Communications Manager (CUCM) 12.5.
Cisco recommends that you have knowledge of these topics:
The information in this document is based on CUCM 12.5 and Unified Computing System (UCS) M6.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
When Virtual Machines (VMs) of CUCM version 12.5 are run on UCS M6 generation hardware with Intel IceLake CPU models (Xeon 43xx / 53xx / 63xx / 83xx), the next error message is observed in serviceability interfaces:
Warning: Intel Processor - this hardware has not undergone upstream testing. Please consult http://wiki.centos.org/FAQ for more information
A similar warning can be seen on UCS M6 hardware with AMD Milan CPU models (3rd-gen EPYC 7xx3):
Warning: AMD Processor - this hardware has not undergone upstream testing. Please consult http://wiki.centos.org/FAQ for more information
A similar warning can be seen on other applications leveraging CUCM 12.5 platform stack.
This is a known and benign error message and can be safely ignored.
This is a kernel-layer error message. It occurs because CUCM 12.5 derives the kernel of its internal OS from the CentOS7 distribution.
At the time CentOS7 was released, the newest CPU models on the M6 server were not yet available for testing by that community.
