Cured. I reverted caffcdd8d27ba78730d5540396ce72ad022aff2c which did nothing as far as I can tell, then I removed the two lines from http://marc.info/?l=linux-kernel&m=140552264825755, then I added back the one line from https://bugzilla.kernel.org/show_bug.cgi?id=80251#c8. I ended up with diff --git a/kernel/sched/core.c b/kernel/sched/core.c index dc2927c..7c3674d 100644 --- a/kernel/sched/core.c +++ b/kernel/sched/core.c @@ -5848,7 +5848,6 @@ build_sched_groups(struct sched_domain *sd, int cpu) group = get_group(i, sdd, &sg); cpumask_clear(sched_group_cpus(sg)); - sg->sgp->power = 0; cpumask_setall(sched_group_mask(sg)); for_each_cpu(j, span) { Thanks. -- Greg Donald
