Every device in the system that uses an IRQ (interrupt request) must use a unique one under FreeBSD. This means that if you want to access your serial port at base 0x3e8 and IRQ 5, no other device can be configured to use either port 0x3e8 nor IRQ 5. You cannot share IRQs with exceptions for multi-port adapters. Many sound cards use irq 5 by default; make sure yours isn't.
