RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

On the x86 platform when there is a corrected MCE error it prints the following messages:
Mar 29 17:52:19 server1 kernel: [Hardware Error]: No human readable MCE decoding support on this CPU type.
Mar 29 17:52:19 server1 kernel: [Hardware Error]: Run the message through 'mcelog --ascii' to decode.

It should however only print them in case of a panic as per the upstream commit:

--------
The "human readable" message is not useful for corrected
errors. There's no reason to run mcelog --ascii and the
error is logged anyways. And it's pr_emerg, which is not
needed for a corrected error.

Only print it during panic.
--------

These messages are confusing to the less experienced admin.

Version-Release number of selected component (if applicable):
RHEL-6.1 beta

How reproducible:
On a system installed with RHEL-6.1 beta with correctable MCE errors you will see these messages.

Steps to Reproduce:
1. Install a machine with RHEL-6.1 beta
2. Wait for MCE errors to be corrected
3.
  
Actual results:
The system logs superfluous messages

Expected results:
These messages should only be printed in case of a panic.
