Ah right, so when do we enable the DART ? Above 1G ? I though it was above 2G but we may well have moved that down to 1G just for b43 indeed. I definitely agree on the fix to the mask so it only compares to the available RAM. I'll check that in when I'm back from the snow fields on tuesday :-) Cheers, Ben, _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
