How about MLIDs from 0xc000 to 0xc07f just to be really safe we should
have it covered ? Also, that's one switch. Can you do this for all the
switches ?

The broadcast group should be everywhere. What ports to LIDs 4 and 16
correspond to ? Are they switch port 0s or HCA ports ?

At this point you have bounded the SM numerous times. Does it work after
first bringing up up the SM and then either bringing up the end nodes
from scratch ?
