Hi Michael. Would you check out.
rpm -q rtirq
and
rpm -q rtload
These two packages should have been installed when you installed 
planetccrma-core with apt-get install planetcccrma-core , and the 
accompanying low latency kernel with apt-get install planetccrma-core-edge . 
These two packages "rtirq" and "rtload" are responsible for realtime working 
with planetccrma kernels. All the best. Nigel.
