Description of problem:
Still seeing this problem I was seeing on 2.6.21-1.3149.fc7.  Appears to be
hanging at "network start" section of boot routine (watching the graphical boot
screen).

I performed a more scientific (?) study this time, starting at a complete power
off state each time (as opposed to rebooting  when I had a successful boot). 
What is interesting is that it failed almost every other time until it started
failing every time.  Boot failed 66% of the time.
