Comment # 66 on bug 1159882 from Robert Delahunt

With cgroup_memory=disable removed (not active) in boot parameters....
(By the way, I only started using that parameter during the process of this bug
testing, so the initial comments I provided when I first began helping didn't
have this...)
This is stock kernel (i.e. opensuse-update)
