It could be that it attempts to access the OSD configuration, like the HDD Utility disc does (And is not supported). Or it could be a result of a deficiency in CDVDMAN/CDVDFSV emulation in both loaders, or is a result of a bug that worsened when CDVDMAN and CDVDFSV were replaced by both loaders during runtime.
