Comment 22 for bug 43114

My newbie mistake, sorry, here is the real cat /proc/swaps output.

Filename Type Size Used Priority/dev/hda3 partition 1389612 0 -1

sudo swapon -av
didn't product any output so I did a

sudo swapoff -av
swapoff on /dev/hda3

Then did,

sudo swapon -av
swapon on /dev/hda3
