Several device drivers hit EEH(Extended Error handling) when triggering kdump on Pseries PowerVM. This patch implemented a reset of the PHBs in pci general code when triggering kdump. PHB reset stop all PCI transactions from normal kernel. We have tested the patch in several enviroments: - direct slot adapters - adapters under the switch - a VF adapter in PowerVM - a VF adapter/adapter in KVM guest.
