From 9b6e9bafa0423ea70ae9c56008e3db7eb9d8ac48 Mon Sep 17 00:00:00 2001 From: Pablo Acevedo Montserrat Date: Wed, 16 Sep 2026 17:18:15 +0200 Subject: [PATCH] OCPBUGS-123681: Disable el98 low-latency presubmit (tuned 2.28.0 regression) tuned 2.28.0-1.el9fdp regressed the [bootloader] plugin so that, on traditionally-deployed rpm-ostree hosts, the microshift-baseline kernel arguments are no longer persisted to the BLS boot entry (tuned-adm returns 0 but /proc/cmdline is unchanged after reboot). This is a real, shipping defect: the low-latency profile is broken in the field for anyone on tuned 2.28.0, so there is nothing valid to gate PRs on until it is fixed. The composer image cannot be pinned to an older tuned (the edge-commit image-type package set requests tuned unversioned, so a blueprint version pin only produces a depsolve "conflicting requests" error), and downgrading tuned at runtime would only produce a false-green against a version the shipped image does not contain. So the scenario is disabled by renaming it with a .disabled suffix (the harness only runs *.sh scenarios), leaving the test intact for an easy revert. Re-enable by renaming the file back to el98-src@low-latency.sh once the fixed tuned build lands in el9fdp. Tracked by OCPBUGS-123681 (depends on tuned RHEL-261119).
