When checking the current state of cyclictest with chrt (chrt -p <pid of cyclictest), it always reported SCHED_OTHER and priority 0. When I tried to change the scheduling policy and/or priority with chrt it seemed to fail as well (not sure whether it tells the truth though). On the other hand starting cyclictest via chrt did the trick: "chrt -f 80 cyclictest..." I can provide further details, when I am closer to the machine in question tomorrow.
