Simple answer: the block is being freed twice. i.e. from a workqueue
during the hibernate process after the relevant memory has been
snapshotted (i.e. because the workqueue was not frozen), and again
after thaw when the memory image is restored to RAM and the
workqueue is started up again and the workqueue runs the same work a
second time.

Cheers,

Dave.
