I'm using CONFIG_PREEMPT all the time. Works fine.
(There are issues with SMP, though).

But what is that:

    printf("No data within twenty seconds. Reseting the ARM\n");
    if(ioctl(frontEnd,74,NULL)==-1) {
      ERROR("Cannot reset the ARM");
      exit(-1);
    }

That's totally bogus, unless you have modified your driver.
