Hm, well, it still shouldn't oops, it should recognize an invalid log format if
one is found.

However, there were some bugs in this area which have been fixed.  See
http://oss.sgi.com/archives/xfs/2006-05/msg00051.html

I can't remember for sure if this led to an oops (Tim?) (feel free to search the
archives)

Can the original reporter try with a recent kernel?  2.6.15 predates that fix.

Also Tim says this:

> 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.
