I just recently upgraded to proposed 0.80.1 instead of ppa.
There are no scrubbing problems in new version.
But my cpu problem looks like is not solved. I suspect cache or erasure coded pools are responsible for problem. But currently I also doing backfilling and data migration so I am not completely sure.
@James, can you create EC pool with cache pool on top of it? Try filling it with few TB of data and check if there is cpu load on idle cluster.
