Looks like a bad sector in the swap partition.
You can probably repair it by using this sequence of commands:
swapoff /dev/sdX <--- replace sdX with actual swap partition dev name
sync
cat /dev/zero > /dev/sdX
mkswap /dev/sdX
swapon /dev/sdX
If it recurs after doing that, then it's time for a new drive.
MS3FGX in linuxquestions says "You can use the -c option of mkswap to check for bad blocks":
sudo swapoff -a
sudo mkswap -c /dev/hdaX
sudo swapon -a
