Michel,
	You had reported that commit 810e95ccd58d91369191aa4ecc9e6d4a10d8d0c8 
was the cause for this bad behavior. Do you see behavior change (from good->bad)
immediately after applying that patch during your bisect process?

Also Michel, double check your .config in both cases.

And also Michel whether CONFIG_FAIR_GROUP_SCHED + CONFIG_FAIR_CGROUP_SCHED
gives more or less same desktop exp as !CONFIG_FAIR_GROUP_SCHED pls!

I would prefer to have CONFIG_FAIR_GROUP_SCHED +
CONFIG_FAIR_CGROUP_SCHED on by default. Can you pls let me know how you
think is the desktop experience with that combination?

I'm going to give that a try but unfortunately, it will have to wait
until I'm back from LCA in a bit more than a week.
