Your shutdown related panic information is interesting. For example,
note the examples of "=deadc0de" in:

QUOTE

         r6 = 0xdeadc0de  r7 = 0xdeadc0de
END QUOTE

looks to me like a "ldr   r2, [r6]" could be the first use of the
deadc0de (happening to be via r6) adn what is leading to the:

'Translation Fault (L1)' on read

I do not know what lead to the deadc0de values.
