Karl, I am assuming that you had a MAXMEM=128MB line before, and it worked? I am a little confused. What happens if you back the changes out entirely? I am running MAXMEM=262720, MAXDSIZ=268435456UL, DFLDSIZ=201326592UL with one de0 device on a P5/133 and 2.1.5R(++) with zero problems. I have a 2.2-CURRENT box I could try it on if we can not figure out your problem, and dropping in another 100baseT card would be easy for me too. One difference between what you have and what I have, is the "UL" token at the end of MAXDSIZ/DFLDSIZ. I have no idea if it could cause what you are seeing. Please provide a little more data and I will see if I can duplicate your problem later this evening. Sorry I can't provide more help, there is not enough data yet. ... JG
