This came up a while ago, see https://groups.google.com/u/1/a/redhat.com/g/aos-devel/c/HuOTwtI4a9I/m/nX9mKjeqAAAJ
Basically this MC:
apiVersion: machineconfiguration.openshift.io/v1 kind: MachineConfig metadata: labels: machineconfiguration.openshift.io/role: worker name: worker-override spec: kernelType: realtime osImageURL: quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:b4cc3995d5fc11e3b22140d8f2f91f78834e86a210325cbf0525a62725f8e099
Will degrade the node with
E0301 21:25:09.234001 3306 writer.go:200] Marking Degraded due to: error running rpm-ostree override remove kernel kernel-core kernel-modules kernel-modules-extra --install kernel-rt-core --install kernel-rt-modules --install kernel-rt-modules-extra --install kernel-rt-kvm: error: Could not depsolve transaction; 1 problem detected: Problem: package kernel-modules-core-5.14.0-282.el9.x86_64 requires kernel-uname-r = 5.14.0-282.el9.x86_64, but none of the providers can be installed - conflicting requests : exit status 1
It's kind of annoying here because the packages to remove are now OS version dependent. A while ago I filed https://github.com/coreos/rpm-ostree/issues/2542 which would push the problem down into rpm-ostree, which is in a better situation to deal with it, and that may be the fix...but it's also pushing the problem down there in a way that's going to be maintenance pain (but, we can deal with that).
It's also possible that we may need to explicitly request installation of `kernel-rt-modules-core`...I'll look.
