You don't need an -rt kernel to hardlock your system with a runaway SCHED_FIFO or SCHED_RR process. It works just as well on a vanilla kernel. To avoid this the only thing you can do is to either a] run a watchdog app (mine is a bit broken atm, so i cannot recommend it) b] do not run SCHED_FIFO or SCHED_RR processes. Using an -rt kernel has nothing to do with it.
