Si una tarea no autorecuperadora que está saliendo ya ha pasado exit_notify() y llama a handle_posix_cpu_timers() desde IRQ, puede ser recuperada por su padre o depurador justo después de unlock_task_sighand(). Si en ese momento se ejecuta un posix_cpu_timer_del() concurrente, no podrá detectar timer->it.cpu.firing != 0: cpu_timer_task_rcu() y/o lock_task_sighand() fallarán.
