Yes, these two are the offenders.  A process should never be for a long
time in "D" state.  You'll have to figure out what these processes are
doing, but they something wrong with these two.

The load average btw is a fairly artificial meassure.  On a properly
working system it describes the burn of the workload of the system
reasonably well - but if things go wrong and cause processes to get
stuck in D state (aka uninterruptible sleep) then a system may well
still be perfectly responsive even though the load is very high.
