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:
IBM is providing a grub patch for PPC systems. This patch will allow grub to retry IO and connection requests to fc devices in the event that the device returns a timeout.
Actual results:
Systems fail to boot with storage related errors.
Expected results:
Systems will no fail to boot.
Additional info:
Adding IBM team to this BZ. As this is affecting some very large customers, there is a heavy push to have this backported into RHEL8.

Sorry, we were busy with other tasks. How far should this go for z-stream ?
We don't currently have any customers on RHEL8 hitting this race condition, but I don't want to wait until 8.5 to release this. I think 8.3.z and 8.4.z is sufficient.

Thanks for the info. Yes, I set to 8.5 because we first need to push the fix in
before backporting to z-stream. As far as I know, 8.3.z is not an EUS release
and was EOL after the 8.4 release, so then we only need to fix this in 8.4.z ?

Please make it available.
