We run Mac IIs with the old EtherPort card, A/UX 2.0 and 5 meg of memory, and 
we never see this (or any other) problem with the cards. It is conceivable 
that the switch to a 68030 with its MMU is causing problems, or even that the 
NuBus timing of the EtherPort card is sufficiently out of spec to cause 
problems with the IIfx. I feel that "Trap Type 4" is going to be significant - 
are these things documented or could someone at Apple enlighten us all? I 
don't know of any tuning things you can do.

>If all else fails, what is the best ethernet card to replace mine with?

A recent message on this group says "Apple Ethernet Card" and that you should 
get one which has the larger on-board memory (revision L, I believe). 
Doubtless Dayna Systems, who took over the new Kinetics EtherPort card, would 
also recommend their product. I think that Dove do an Ethernet card as well.
