Most filesystems are silent when they are given a superblock
that they don't recognize.  cramfs still has the debugging
message "wrong magic", and it will give this message even if
the superblock is later recognized by ext2fs.  So probably
the message that you would like to see is probably "ext2:
superblock not recognized".

Make sure that it's trying to mount the correct partition and
that the .config has your flavor of fs enabled.
