Rob, after I posted that I tried updating my drivers for my NIC with the latest from Intel's site directly. Since I have done that my problem has gone away and I before trying that I was guaranteed within 2 hours of use each time every time I would blue screen.
I have been testing this for a month now almost without problem.
Try getting your drivers from here and see if this fixes you:
