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 2 John Ferlan 2021-11-17 14:27:08 UTC 
Philippe - assigning directly to you since you own the RHEL9 clone bug 2007932
Comment 4 Klaus Heinrich Kiwi 2022-01-03 14:05:24 UTC 
It's always a dilemma whether to have duplicate bugs for each version before reaching a solution, or after. I'll keep this where it is, but with a lower priority and a dependency to Bug 2007932, but for next time, let's consider having the bug tracking only nextrelease (or the latest released version if it's not reproducible in the nextrelease), and create duplicates only when we make a determination that the root cause has been found/fixed, and we need to bring those to N-1/N-2 releases ...
Comment 7 Klaus Heinrich Kiwi 2022-02-07 14:29:55 UTC 
Assigning to Stefan for consistency with Bug 2007932, where the investigation is actually happening

Actually doing this now
Comment 10 Tingting Mao 2022-08-11 08:35:16 UTC 
Not hit the issue in latest rhel8. So close it now.
