Log replay is certainly not endian independent but it can handle
different word-size machines nowadays (didn't in the past).
So you can go between i386 and x86_64 for example, with a dirty log.
The log formats will be different between the two for some items
but in recovery with a newer kernel we do conversion on the fly.

It certainly does sound like that is the issue here, Chris.
The back trace is just like a typical different log format problem.
