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.

We recently re-hired two Power8 machines for Fedora Copr build system,
but it seems that we can not build packages against the pre-release
centos-stream-9-ppc64le chroot because of this mock failure:

...
  Running scriptlet: util-linux-core-2.37-1.el9.ppc64le                  92/160 
Fatal glibc error: CPU lacks ISA 3.00 support (POWER9 or later required)
warning: %post(util-linux-core-2.37-1.el9.ppc64le) scriptlet failed, exit status 127
...

Full log: https://download.copr-dev.fedorainfracloud.org/results/praiskup/ping/centos-stream-9-ppc64le/02135293-dummy-pkg/builder-live.log.gz

It may be expected, though I'm rather asking..   Is the EL9 supposed
to be Power9 only?
