Raspberry Pi B+ - swap failure on boot

cat /etc/fstab

/dev/mmcsd0s1   /boot/msdos     msdosfs rw,noatime      0 0
/dev/mmcsd0s2a  /               ufs rw,noatime          1 1

md99            none            swap sw,file=/usr/swap0 0 0

After boot:

$ swapinfo
Device          1K-blocks     Used    Avail Capacity

$ swapon -a
swapon: md99 on /usr/swap0: Device already in use

$ swapinfo
Device          1K-blocks     Used    Avail Capacity

$ swapoff -a
- no output -

$ swapon -a
swapon: md99 on /usr/swap0: Device already in use

$ swapinfo
Device          1K-blocks     Used    Avail Capacity

If I comment the entry in fstab, reboot, then uncomment it after logging 
in, it works as expected.
