If the serial section of your UEFI/BIOS has IRDA support, you want to disable that if you just want to use a standard serial port.

[DNG] no ttyS0 - Chimaera, vanilla kernel 5.10.0-10 on Atom C2750
Greetings Devuan! I am trying to use onboard RS-232 @ supermicro A1Sai-2750 with Intel C2750, Devuan Chimaera, vanilla kernel 5.10.0-10-amd64. In BIOS the ports COM1 and COM2 are configured on 24MHz/13. In dmesg I can see: "/Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled/" but no tty (except console), and receive IO errors on /cat /dev/ttySx/, and on /stty -F /dev/ttySx/ Searching brought me to the kernel rebuild with options like CONFIG_SERIAL_8250_PCI, which are already enabled in current kernel. Tried to load 8250_lpss.ko too, with no luck. Shortcut would be to use the USB RS-232 dongle, however it will be too easy, I guess, and boring too. Can you give me some light, please? Many thanks!
