https://git.kernel.org/cgit/linux/kernel/git/powerpc/linux.git/commit/?h=fixes&id=1bc74f1ccd457832dc515fc1febe6655985fdcd2 powerpc/powernv: Fix stale PE primary bus When PCI bus is unplugged during full hotplug for EEH recovery, the platform PE instance (struct pnv_ioda_pe) isn't released and it dereferences the stale PCI bus that has been released. It leads to kernel crash when referring to the stale PCI bus. This fixes the issue by correcting the PE's primary bus when it's oneline at plugging time, in pnv_pci_dma_bus_setup() which is to be called by pcibios_fixup_bus(). ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Taco Screen team (taco-screen-team) Status: New ** Tags: architecture-ppc64le bugnameltc-134012 severity-critical targetmilestone-inin1604 ** Tags added: architecture-ppc64le bugnameltc-134012 severity-critical targetmilestone-inin1604 ** Changed in: ubuntu Assignee: (unassigned) => Taco Screen team (taco-screen-team) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1546145 Title: Surelock-GA2:kernel panic @ cxl_configure_adapter+0x418/0x8b0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1546145/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
