With my current pae patches (but PAE disabled) right after
loading and starting domain0, before some message from the
xenlinux kernel appears.  With a unmodified bk checkout it
dies later on while xenlinux domain0 processes the init
scripts, but it's the same pattern.

I'd guess it's pure luck whenever you are hit by it or not.
Maybe it is memory corruption.  The faulting address not
being in the extable and not even being a valid instruction
looks like a random jump into nowhere ...
