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.
