I'll start by saying I don't know much about FDT (I only first heard of
it a couple weeks ago, and it's now high on my "learn more about this"
list)...
I notice the backtrace shows signs of the crash being interrupt-related,
and boot output included a complaint about "no handler for pin 34", and
the FDT gpio block lists a bunch of pins in the interrupts= line but not
34. Could it be as easy as adding 34 to that list?
