The possible reason could be that driver calls tty_register_devfs itself in this case it must set TTY_DRIVER_NO_DEVFS flag to prevent the same nodes registered by tty_register_driver. -andrej > devfs_register(cua): could not append to parent, err: -17 > tty00 at 0xbfbd9830 (irq = 29) is a Zilog8530 > tty01 at 0xbfbd9838 (irq = 29) is a Zilog8530 > > The result is that the directories /dev/tts and /dev/cua are missing. > > There are only the files /dev/ttS and /dev/cua which can be used to get > access to the first serial port. > > I have attached the full dmesg output at the end. > > Regards > > Raoul
