What's the problem?  This is the standard way for Linux to name serial
ports.  3F8 gets /dev/ttyS0 and 2F8 gets /dev/ttyS1.  That is working
as designed.  I would be more concerned about /dev/ttyS2 and /dev/ttyS3
sharing IRQ 9.  IRQ sharing usually doesn't work with serial ports.
Also, IRQ 9 is normally used by the ACPI controller.
