No idea, but it doesn't implement ppc_md.pci_get_legacy_ide_irq(). Only Maple does -- maybe the others actually manage to route it to IRQ 14 and 15? Perhaps we could do that on Maple too -- after all, IRQ numbers in Linux are just a fiction which don't have to match the hardware documentation in any way. -- dwmw2
