Let me add a couple comments to this:

1) I get the resetting chip on occasion when doing extending networking,
such as a cvs up, even with the MP

2) I do not have the performance problems with mc on an MP system.

I have not had time to review the differences (if any) of DBDMA handling
between MP and SP, but given the above, I suspect something is being
handled differently. Since I get the resetting chip note even with MP, I
don't immediately conclude the two problems are related.
