From 4e23e134063807a9288e9b547e1955a9124ac5b7 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 18 Jul 2011 17:03:52 +0200 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.
