So, I'm really quite baffled right now. Any ideas would be welcome, I'm sort of stumped. In particular since pasemi_defconfig boots fine.
So you are coming in with "good" endian... what if you stick an isync in there just for fun ? I wonder if it prefetches the "bad" instructions and somewhat gets itself confused. Also did you try sticking a b . around 0x700 see if that's where it's going and what condition gets set ? Cheers, Ben.
