Peter, do you think it would be worthwile to test a kernel with the
low load-averages in NOHZ=disable mode? The bisected commit claims to
fix a NOHZ issue with the load average. So if the new figures are the
correct ones, they should be somehow similar to the figures before
with NOHZ? Or am I on the wrong track here?
Regards,
Flo
