Edit the cryptswap1 entry in /etc/crypttab to identify the swap device by 
its device path (/dev/sda2), or by its disk by-id path
(example: /dev/disk/by-id/ata-HDMANUFACTURER-MODEL-SERIALNUM-part2). If 
you have multiple hard disks attached to your system then use disk by-id. 
So your crypttab should contain a line like this:

cryptswap1   /dev/sda2    /dev/urandom  swap,cipher=aes-cbc-essiv:sha256
