Following up. For all of us with clusters still using Linux 6.10 with active/backup bonding, the wait is over with the release of .30.2 kernel. For Red Hat Enterprise Linux systems, see RHSA-2020:2430 For Oracle Linux systems, see ELSA-2020-2430 We have tested this on HPE hardware with network switch port disablement. Looks like the correction works.
