Subject: sched: Disable CONFIG_RT_GROUP_SCHED on RT From: Thomas Gleixner Date: Mon Jul 18 17:03:52 2011 +0200 From: Thomas Gleixner 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.
