It probably shouldn't be a release blocker because it doesn't prevent the 
system from functioning correctly but it's certainly a problem and it will 
probably debugging other issues harder because nobody can tell if elevated 
load is the result of the reported problem or this bug.

FWIW "nohz=off" seems to fix the high load problem for me although I still 
see the load balancer accounting for most of the wakup calls in powertop 
(which might or might no be an actual problem).
