This is because the reiserfs superblock is 64kB into the filesystem, and it appears that the mkfs.xfs does not overwrite this part of the disk. I have heard of another person with this same problem. It would probably behoove the XFS folks to zero the first and last 128kB of a partition when doing mkfs.xfs to avoid this sort of problem. For mkfs.ext2, it will zero the first 4kB, overwrite the next tens of kB, and also zero the last 128kB. I should probably make sure that it will _always_ overwrite at least the first 68kB, but with the default parameters it will at least do so except on the smallest of filesystems (i.e. floppies).
