The PE number (@frozen_pe_no), filled by opal_pci_next_error() is in big-endian format. It should be converted to CPU-endian before it is passed to opal_pci_eeh_freeze_clear() when clearing the frozen state if the PE is invalid one. As Michael Ellerman pointed out, the issue is also detected by sparse: eeh-powernv.c:1541:41: warning: incorrect type in argument 2 (different base types) This passes CPU-endian PE number to opal_pci_eeh_freeze_clear() and it should be part of commit <0f36db77643b> ("powerpc/eeh: Fix wrong printed PE number"), which was merged to 4.3 kernel.
