Please enable CONFIG_RT_GROUP_SCHED!
I'd really like to see this option enabled because it would allow it for the
first time in Linux history to run normal user applications with rt scheduling
in a secure way, i.e. without allowing them to lockup the machine. PulseAudio
would greatly benefit if we could enable RT scheduling for it by default.
I wonder however, if http://bugzilla.kernel.org/show_bug.cgi?id=10361 might
become a problem.
Looks like its in the latest kernel in koji
