我有一个小型/廉价的家用 NAS，用于备份和其他大容量存储。它有一个 SATA 卡，有 8 个端口，可连接 8 个驱动器。该卡使用 ASM1064 芯片组和 JB575 端口倍增器。
升级到 24.04 服务器后，卡上的 8 个端口中只有 4 个可以正常工作。
当我将磁盘连接到一个非工作端口时，收到以下消息：
[ 1254.035054] DMAR: DRHD: handling fault status reg 2
[ 1254.035087] DMAR: [DMA Write NO_PASID] Request device [01:00.0] fault addr 0x66f6c000 [fault reason 0x05] PTE Write access is not set
如果我启动 23.10 实时 CD，所有 8 个端口都可以工作。
