The eeh_driver disables and offlines the PE permanently when it exceeds the freeze count beyond eeh_max_freeze within the last hour. The PE is only offline, so the device tree entries, eeh device references are all intact till the real unplug of the device from the guest/host takes place. On pSeries, with a new hotplug of any PCI device, the drmgr initiates a system-wide PCI rescan, which finds devices offlined by the eeh_driver and there will be attempts to bring them online. This leads to recurring EEHs either at the config read time itself or a bit later depending on the type of the problem. [...]
Applied to powerpc/fixes.
