It could be that the blocks appear multiple times in the file; or it
could be the storage system is returning different data on subsequent
reads from the device.

What we need is a debugfs dump of the inode on the file system that is
having trouble.  A debugfs dump of the inode from a completely
underlated file system is not useful....
