I have to admit, that PCI I/O can't have worked until now on Yosemite/Yellowstone. I just found a bug in arch/ppc/platforms/4xx/yosemite.h: -#define YOSEMITE_PCI_IO_BASE 0x00000000e0000000ULL +#define YOSEMITE_PCI_IO_BASE 0x00000000e8000000ULL Please give it a try and let me know if the problem is fixed. Best regards, Stefan
