  Modified files:
    sys/powerpc/powerpc  busdma_machdep.c 
  Log:
   The nsegs parameter to bus_dmamap_load_mbuf_sg is not required to
  be set to 0 on input. This caused a panic in an an MP test version
  of the GEM driver from Marius, and from inspection of other PCI
  drivers, the same problem would happen there.
   Fix by explicitly setting to 0.
