      Sad that even this documentation is locked behind a Redhat account, I can only read part of the problem description. Not going to make an account because it really doesn't affect me right now.

        I made a free account.
        Resolution
        The issue has been resolved with the errata: RHBA-2025:4337. Hence, update the kernel to kernel-4.18.0-553.51.1.el8_10 to fix the issue.

        id assume it arrives soon? I as well, haven't seen it yet.

            I just updated an Alma 8 and it has the .51 kernel now.

              I just updated an Alma 8 and it has the .51 kernel now.

              Tried one of my Rocky's and still .50. I wonder where we can see the status of downstream fixes like that? anyone know? thanks.

                This may sound stupid, but here goes...

                Does Rocky need to update to .50 before it can update to .51?

                I'd guess no, but I've been away from RHEL based stuff since the IBM rug pull. Only coming back because I may need it in the future as I jockey around trying to improve my paycheck.

                    Alma must have dropped everything to push this out. I wonder what Oracle is doing, guessing they were hit by this too. I'd guess Rocky has this out pretty fast, they know it is important.

                      I updated my Redhat 8 instances to the .51 kernel and it's back to working.

                      This update addresses various issues and includes enhancements to improve system stability and performance. For detailed information about the fixes and improvements in this release, you can refer to the official Red Hat advisory.
