It very much looks like the disk is dying. Dunno why it doesn't show up
during SMART testing but you better back up and contact the hardware vendor.

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.

Hmmmm... Does Power-Off_Retract_Count increase after suspend/resume cycle?
