There's a theoretical potential for the system to crash in -rt when unloading a module. Simply because interrupts are threads. Some device has an interrupt handler that is called and preempted. At that moment the module for that device is unloaded. This calls things like kstop_machine that should make sure that all interrupt handlers have been resolved. But this does not work with -rt, since the interrupt handlers can now be preempted and resume after the kstop_machine and the moduling being unloaded. Since the code for the interrupt handler no longer exists... KABOOM!
