Hello, I built a kernel where the serial core and 8250 code will be in a module and not built in. But now there is no /dev/ttyS0 after a reboot. only /dev/ttyS1/2/3. If i mknod it manually it works fine. in the previous kernel, after a reboot I already had /dev/ttyS0. Where can I start check for the problem ? I know udev is making the /dev/ttyS0 but where is the code in the kernel that is supposed to send the command ?
