From: Thomas Gleixner Date: Mon, 18 Jul 2011 17:03:52 +0200 Subject: [PATCH 045/342] sched: Disable CONFIG_RT_GROUP_SCHED on RT Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=35fe4c7ed5f8c8dbd6fc8dbc4ea79f38e6709cbc Carsten reported problems when running: taskset 01 chrt -f 1 sleep 1 from within rc.local on a F15 machine. The task stays running and never gets on the run queue because some of the run queues have rt_throttled=1 which does not go away. Works nice from a ssh login shell. Disabling CONFIG_RT_GROUP_SCHED solves that as well.
