I also had the kernel crash (I tried with a 3.5 and a 3.6 kernel).
Changing defaultdisplay from lcd43 to dvi allowed the system to boot.
But there's no output on the LCD with that setting.  How can I enable
the LCD if the uboot env variable must be set to dvi in order to work
around the crash?  LCD works fine with a 3.4 kernel
