Which kind of implies that we've got a bogus fsbno
that we're using as the basis of allocation.....

What is the corruption you are inducing? Can you produce
a xfs_metadump image of the filesystem and put it up somewhere
that we can access it?

I suspect that we are not validating the block numbers coming
out of the various btrees as landing inside the filesystem....

Cheers,

Dave.
