I have a FreeBSD system running on an Intel brand motherboard with a 945G chipset - while it doesen't do the thing with the pings he's talking about, take a look at the following dmesg snippet: sio0: configured irq 4 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 sio0: type 16550A However, despite this the serial port does work. I always thought this was some harmless bug in the sio code but I wonder now if these problems are related and it's a bug in the chipset driver in FreeBSD. Could you post your entire dmesg output, please?
