On PowerPC, the interrupts are used only for debugging. Why is this necessary? The interrupts were enabled for all architectures before. However, this patch is wrong as J?rgen mentioned, the SIER_FLAGS are written to the SIER register after we enable the DMA enable bits which leads to missing DMA enable bits at the end. I created a new patch to cleanup the whole interrupt flag setup. I will post it later.
