There are a few patches that fix race conditions and crashes using CFS_BANDWIDTH that have been identified here: https://lkml.org/lkml/2013/10/16/818 I've already submitted "sched: Avoid throttle_cfs_rq racing with period_timer stopping" to stable as it fixed an immediate issue I was seeing; however these other patches fix related bugs that could also be problematic. The commits are the following: commit 1ee14e6c8cddeeb8a490d7b54cd9016e4bb900b4 Author: Ben Segall <bsegall@xxxxxxxxxx> Date: Wed Oct 16 11:16:12 2013 -0700 sched: Fix race on toggling cfs_bandwidth_used commit db06e78cc13d70f10877e0557becc88ab3ad2be8 Author: Ben Segall <bsegall@xxxxxxxxxx> Date: Wed Oct 16 11:16:17 2013 -0700 sched: Fix cfs_bandwidth misuse of hrtimer_expires_remaining commit 927b54fccbf04207ec92f669dce6806848cbec7d Author: Ben Segall <bsegall@xxxxxxxxxx> Date: Wed Oct 16 11:16:22 2013 -0700 sched: Fix hrtimer_cancel()/rq->lock deadlock commit 0ac9b1c21874d2490331233b3242085f8151e166 Author: Paul Turner <pjt@xxxxxxxxxx> Date: Wed Oct 16 11:16:27 2013 -0700 sched: Guarantee new group-entities always have weight These cleanly cherry-pick in all branches from 3.4.y - 3.12.y and I've build tested them after applying the patch.
