This one is ok.

This one has the exact same odds values for system.slice->tg_load_avg
than the 1st dump that you sent yesterday
The dump indicates Sched Debug Version: v0.11, 4.8.0-22-generic #24-Ubuntu
So this dump has been done with a different kernel than for the dump above.
As I can't find any stress task in the dump, i tend to believe that
the dump has been done before starting the stress tasks and not after
starting them. Can you confirm ?

If i'm right, it mean that the problem was already there before
starting stress tasks."
