| 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. |
