Any E100/Beagleboard users running into realtime scheduling issues?

Out of curiosity are there any USRP E100 users running into problems
enabling realtime scheduling? On my beagleboard I am not able to use
realtime scheduling since upgrading to the latest kernel and Angstrom.
Apparently there is an issue with realtime scheduling being done on per
group basis or something like that, which is weird since I was doing
everything as root.

Anyways I managed to fix this issue by

echo -1 > /proc/sys/kernel/sched_rt_runtime

which apparently was reserving 95% of the CPU time for realtime threads
which even as root I wasn’t able to access. Anyways, I’m interested
from hearing if someone else faced this and if there’s a neater solution
