Robert Thank you so much for the reply. I was unaware that I could pull diagnostic information from the BBB during boot from the serial port.
Indeed - I never noticed the serial port before either! I believe I have a serial to USB adapter, so I'll try it when I get home. One correction: my flashed BBB is not running Ubuntu 12.4, but 13.04. Not that it makes a difference, but I figure for historical reasons I'd correct it. Thanks again for your help. I am sure dealing with newbies all the time must be frustrating. I do know a lot of stuff, but am relatively new to Linux, ARM, etc..
