The problem was that one bus_dma_tag_create (at line 300) was failing to create dma tag, and was returning So I changed the flag from BUS_DMA_ALLOCNOW to BUS_DMA_COHERENT and the driver was loading and was working. Now, I have no idea what these two flags mean or the changed I made are appropriate. Any way I am off to file a PR against safe.c raj
