While it is true that filesystem superblocks contain magic numbers, it doesn't imply that every magic number has something to do with filesystem superblocks. Magic numbers are used throughout the kernel to check if structures passed to a function are indeed correct: if the magic number fails, it is a sign that something is wrong with the structure. It could be corrupted by something, it could also be that the user forgot to set the number. Without seeing the code, it's hard to tell what's wrong.
