How much bandwidth does the SCHED_DEADLINE taskset consume ? 100% ?
I launched it with 33%
rt-app -t 3000:1000:d

Which kernel are you using ? Any way of trying 3.14 ? (which already has SCHED_DEADLINE merged)
I am trying kernel 3.14... otherwise SCHED_DEADLINE won't be there ;)
The description of what I did can be found here: http://www.icarusrobotics.com/?p=1187 You will find debian packages to install yourself the kernel I am using on your Ubuntu machine (if you have one). But, in short, I used
PREEMP_RT patch patch-3.14.0-rt1

Saw the same here. 3.14-rt1 has problems running SCHED_DEADLINE tasks (note that it is the first release on top of 3.14). It is not an rt-app problem, though. Hope to find out a solution soon.
Thanks!
The title says it all. I used rt-app to create a periodic task and my PC freezes completely when the kernel used is patched with PREEMPT_RT.
Any clues? Any suggestion about how I can debug this problem?
