Can you apply the appended patch and boot with earlyprintk=serial 
(+ serial console with 38400 baud on ttyS0 and a terminal program
that does logging on the other side). If you don't have a serial
console you can also use earlyprintk=vga , but that would require
writing down what's on the screen.

What does it say?
