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
