Description: (from RedHat's bug tracker)
<Lennart Poettering 2015-06-09 09:05:59 EDT> "I am pretty sure that CONFIG_RT_GROUP_SCHED should be turned off in Fedora, as there's no way to make use of it in a sane way right now. If turned on, and there's any cgroup in the "cpu" hierarchy it needs an RT budget assigned, otherwise the processes in it will not be able to get RT at all. THis then shows up in bugs like 655321."
