QEMU fails when used with the following command line: ./ppc64-softmmu/qemu-system-ppc64 -S -machine 40p -device i82374 qemu-system-ppc64: hw/isa/isa-bus.c:110: isa_bus_dma: Assertion `!bus->dma[0] && !bus->dma[1]' failed. The 40p machine type already creates the device i82374. If specified in the command line, it will try to create it again, hence generating the error. The function isa_bus_dma() isn't supposed to be called twice for the same bus. Check the bus doesn't already have a DMA controller registered before creating the device.
