Hi,

i have RTnet 0.9.11 running. Sometimes the Console stalls on a call to
`rtifconfig <dev> down`.

I don`t know if it might be caused by using realtime spinlocks in non
realtime context as it is done in rtnet_chrdev.c at line 168 for
example. I have copied the a part of this code so you can have a quick
look at it:

        case IOC_RT_IFDOWN:
            if (mutex_lock_interruptible(&rtdev->nrt_lock))
                return -ERESTARTSYS;

            /* spin lock required for sync with routing code */
            rtdm_lock_get_irqsave(&rtdev->rtdev_lock, context);

Tobi
