covered in https://gitlab.freedesktop.org/NetworkManager/NetworkManager-ci/-/merge_requests/964 regression found: https://bugzilla.redhat.com/show_bug.cgi?id=2055665 This is unfixed as fixes for #2047302 or #2029937 or 2022275 broke it again. Exception request notes: ======= Impact Statement ======= What is the benefit of making this change after the deadline? What is the impact on customer satisfaction, and on the business? The OpenvSwitch plugin of NetworkManager is widely used in RHV and CNV team. Deleting an OpenvSwtich bridge is considered as key function. The problem was fixed by early rpm build of 8.6, but then been reintroduced by late patches. What is the risk to the release schedule, quality, and the impact of diverting resources from other efforts? Will there be enough time to do the necessary large-scale, cross-function, regression, stress, or fault-insertion testing that may be required to verify this change? Upstream has merged the patch. Scratch build been tested at comment #17 CI has confirmed no regression been introduced for know use cases. NetworkManager QE(Vladimír Beneš <vbenes>) confirmed there is enough resources for testing new rpm build as the CI results only require up to 2 days for log vetting. failing with RHEL-8.6.0-20220308.2 and not failing with RHEL-8.6.0-20220318.d.0 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
