I'm not so sure that this is a duplicate of that bug. I did not have the proprietary drivers installed when I upgraded. This bug should have nothing to do with the proprietary drivers.
I think this is a race condition durring boot. The last two boots were sucessfull I think because I was continuously moving the mouse. The last 20 or so boots failed unless I disconnected the HDMI cable.
