Dispositivo não reivindicado no lshw

Question

Eu adicionei no meu computador uma placa controladora PCI Express com 2 portas USB3 e 2 portas sata3. ( link ).

As portas USB estão funcionando corretamente, mas o HDD conectado à porta sata não está aparecendo nos dispositivos.

Eu rodei o lshw e aqui o resultado referente ao cartão pci:

*-pci:1
            description: PCI bridge

Parece que o IDE não reivindicado é o culpado e que não foi reivindicado porque o sistema não encontrou nenhum driver para ele. Como posso encontrar qual driver eu precisaria para que essa parte ide funcionasse?

Até agora, minha pesquisa no Google por PEX 8604 não retorna quase nada em relação a um driver Linux.

Answer 1

Eu encontrei a solução. O dispositivo não foi reivindicado porque não era conhecido corretamente pelo kernel.

Usando um kernel 3.5, o dispositivo foi listado como abaixo:

*-ide UNCLAIMED
               description: IDE interface
               product: ASM1061 SATA IDE Controller
               vendor: ASMedia Technology Inc.

               bus info: pci@0000:07:00.0
               version: 01
               width: 32 bits
               clock: 33MHz
               capabilities: ide msi pm pciexpress cap_list
               configuration: latency=0
               resources: ioport:7000(size=8) ioport:7400(size=4) ioport:7800(size=8) ioport:7c00(size=4) ioport:8000(size=16) memory:d6100000-d6100

mas ainda não foi reivindicado.

Ao pesquisar pelo dispositivo [1b21: 0611], encontrei uma postagem a lista de discussão do kernel falando sobre isso. Ele informa que o kernel não identifica o dispositivo corretamente como um dispositivo ahci e propõe um patch para o kernel.

/* Generic, PCI class code for AHCI */

Eu apliquei o patch na fonte do kernel 3.5 e recompilei e agora está funcionando. Para informação, o patch está incluído no kernel na versão 3.6 e acima.
