I was hoping to avoid learning how to build kernels with debug messages but I suppose it's a good skill to have. :-) > Alternately you could stare at the driver sources until enlightenment > occurs. I did a little of this and superficially it does seem like there could be differences between FreeBSD and Linux in the treatment of the mysterious 6th port (SEMB) on the 5-port multiplier. Hopefully, the logging you suggest will clarify the situation.
