The more I think about it the more i think this is a network bug. I ran my system succesfully for over 8 hours no problems and "no internet".
So the question is "us with the bug, what do we have or do different to those without.
So question to anyone who doesn't have it, did you change anything network related since you installed leopard? Different IONetworkfamily.kext? Etc?
For those who do have it, are you like me no changes to network since installation. Also any thing else anyone can think of, I'm thinking this must be something really simple and really subtle as some don't and some do and there doesn't seem any apparent link, what are we all missing?
