 * Deleting and recreating test workloads with a BlueField-3 NIC causes clock jumps due to inconsistent PTP synchronization. This disrupts time synchronization in test workloads. The time synchronization stabilizes when the workloads are stable. (link:https://issues.redhat.com/browse/RHEL-93579[RHEL-93579])
 
 * Currently, Extended Update Support (EUS) to EUS image-based upgrades are not supported on clusters that have cert-manager installed. As a workaround, remove cert-manager before performing the image-based upgrade, and reinstall it after the upgrade completes. (link:https://issues.redhat.com/browse/OCPBUGS-86967[OCPBUGS-86967])
+
+* Currently, the `ListenerSet` custom resource definition (CRD) is installed on the cluster, but the {product-title} Gateway API implementation does not support `ListenerSet` resources. As a consequence, a `ListenerSet` that targets a {product-title}-managed `Gateway` is not reconciled, and the listeners that it defines are not programmed onto the `Gateway` and do not route traffic. The `ListenerSet` reports an `Accepted=False` status condition with the `UnsupportedByController` reason, and the `ListenerSetOnManagedGateway` alert fires. As a workaround, define listeners directly on the `Gateway` resource instead of using a `ListenerSet`. (link:https://redhat.atlassian.net/browse/OCPBUGS-100435[OCPBUGS-100435])
