The recovery was resumed from a previous checkpoint. I guess you
rebooted or stopped the array during recovery?
At any rate, md doesn't calculate resync speed correctly for
checkpointed or bitmapped resyncs (it assumes that the skipped portion
was actually resynced).
Neil fairly recently sent in patches to fix this, but I think they won't
be in mainline until 2.6.18 or so.
