Your super block got corrupted somehow or you have your partition table 
changed so that the blocknumber of the superblock was changed.

To rebuild the corrupted superblock you can use reiserfsck --rebuild-sb.

We decided to not provide a special exit code for corrupted super block
to avoid an automation of super block recovery. This is a difficult case 
and should be done manually.
