I think CityK confirmed that the nxt2004 driver statistics are probably bogus so
I doubt you're going to get your 115's running with BER 0 regardless, which is
unfortunate.
Assuming your original configuration was fine, the second part of the problem
remains then.... is the DMA being screwed by the mix of boards.
I'm not sure I have an easy way for you to determine this, other than making
sure everything is on it's own interrupt, going back to basics to a single 115
and a single 250 and trying to isolate the changes step by step.
