------- Comment From boris.m...@de.ibm.com 2025-03-25 07:55 EDT------- Thanks for confirming that the fix is already included in Ubuntu 25.04.
With this being already part of the current release, can we get the fix also into the latest LTS release Noble via SRU? (I don't want to prematurely exclude Jammy explicitly, but considering backport effort and risk, we might want to focus on Noble only.) ** Tags removed: targetmilestone-inin2504 ** Tags added: targetmilestone-inin2404 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2104120 Title: [Ubuntu 25.04] s390/pci: Fix PCHID per port multi-function detection Status in Ubuntu on IBM z Systems: Fix Released Status in linux package in Ubuntu: Fix Released Bug description: Description: s390/pci: Fix PCHID per port multi-function detection Symptom: There are two cases in which PCI functions are incorrectly placed, or not placed, in a shared PCI topology. In the first case a PCI physical function (PF) which is initially in standby was incorrectly not creating a new PCI topology when hotplugged, but would if configured during boot. In the second case a PCI virtual function (VF) would be placed in the shared PCI topology of a PF if that PF is from the same card even if the parent PF is not in the configuration which should lead the VF to be isolated in its own single function topology. Problem: Both problems are caused by logic bugs in the determination of which PCI functions create topologies and when a PCI function may be added to an existing topology.
