I have and can confirm that several of the issues appear to be fixed, but
yet there are a few more that arent. Enabling anything that makes large use
of socket, and or IP code is still a problem. In other words I am not sure
the netisr problem is quite yet fixed. I am going to try a couple of tests
and see what happens
