I added an old SGI boot parameter to tell it to go away. You're talking about the rt badnwidth timer, right? 1) why won't it go away with DL added? 2) it should never appear when !rt_bandwidth_enabled(), so if you set sysctl_sched_rt_runtime to -1 all this should go away already, no extra patches required.
