Bug Description
== Comment: #18 - Andrew Donnellan - 2016-02-15 20:17:01 ==
Canonical kernel team - please apply 1bc74f1ccd45783
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_
be called by pcibios_
