+Subject: [PATCH 190/323] sched: Disable CONFIG_RT_GROUP_SCHED on RT
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+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.
