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.

Comment 10 Michal Polovka 2022-01-17 15:23:10 UTC 
As the verification is blocked by https://issues.redhat.com/browse/IDMOPS-571, we are forced to move this BZ to later ITM (21).
Comment 14 Florence Blanc-Renaud 2022-01-19 15:07:30 UTC 
Moving back to ON_QA, the move to Verified:FailedQA was a human error.
Comment 17 Florence Blanc-Renaud 2022-03-17 13:24:59 UTC 
The BZ has also been detected on RHEL 8.4 and RHEL 8.5, hence asking for z-stream for those releases (see BZ 2065038 and BZ 2065040).

@tapazogl can you provide zstream+ ? thanks
