A placa-mãe. Mais especificamente, o BIOS. Ele está apenas dizendo que o ASPM (modo de economia de energia para o barramento pcie quando está ocioso) está sendo desativado como resultado, então simplesmente ignore-o.

O kernel está relatando que o firmware se recusou a passar o controle da funcionalidade PCIe para o kernel. _OSC é um método de controle ACPI que o kernel usa para ver se o firmware (BIOS) permitirá que ele controle PCIe Gerenciamento de energia do estado ativo (entre outras coisas).

Esta é apenas uma mensagem de aviso e não um bug.
