I have to echo this advice. While RTLinux and other RTOS'es have great interrupt latency performance, using those interrupts to trigger sampling on an ADC is a bad idea. It won't work at all if you are trying to sample faster than about 1-10 kHz, and the jitter is horrible even below that. Even a great RTOS will only get you about 10us repeatability. It is always best to use a real oscillator to trigger sampling. For some reason, interrupt-based sampling seems very popular in the radio astronomy world.
