Thanks a bunch for the tip (see below)

Action taken:
issued sudo swapon -a
got: swapon: Cannot find the device for UUID+fc3d...

changed the entry in /etc/fstab to use /dev/sda5 instead of the UUID value.

reissued the sudo swapon -a command, it worked and top now shows the expected 
value for swap.

The Hibernate entry still does not show, however, I expect that a reboot will 
solve that. If not how do I proceed?

Note: I had noticed a message during boot about device with the same UUID as 
being not ready but since the system continued to boot and came up I figured 
that all was OK. WRONG!

Cheers,
Jay
