Recentemente eu configurei um novo servidor com o Ubuntu Server 12.04. O modelo da placa-mãe é: Gigabyte H81M-DS2V. Eu acho que tenho algum problema com os drivers. Aqui está a saída de lshw :

Eu tenho o mesmo caso: 

    *-serial UNCLAIMED

         configuration: latency=0

dmesg | grep -i conflict

dmesg | grep ACPI

[   19.286144] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

Parece que a ACPI está manipulando o dispositivo em vez do driver nativo. Apenas para confirmar, inicializei minha máquina com acpi=off , o driver nativo ( i801_smbus ) foi usado: 

    *-serial

         product: 5 Series/3400 Series Chipset SMBus Controller
         vendor: Intel Corporation
         physical id: 1f.3

         version: 05
         width: 64 bits
         clock: 33MHz
         configuration: driver=i801_smbus latency=0
         resources: irq:18 memory:e9630000-e96300ff ioport:8000(size=32)

Para esse *-power device, não consegui fazer nenhum avanço.
