Hi What may happen on a SMP machine if a serial port has been closed and the closing stage is at shutdown() in serial.c in the call to free_IRQ and BEFORE the IRQ is really shutdown, a new character arrives which causes an IRQ? Is it possible that the OTHER cpu takes this interrupt and causes a crash?
