Absolutely 100% udevd related.  It always pops right when udev starts.
Every time.  I don't know how to get that to come out on the serial
port, you only get to see the kernel messages (although there is nothing
on the screen other than "Starting udev"

Reverting 3f2aa307c4d26b4ed6509d0a79e8254c9e07e921 causes the problem to
go away.  I now am running a 79b520e87e kernel + your patch (adding
console_verbose()) + reverting 3f2aa307c4d2 and it seems to be working.
