如您所见，它每秒发送数十次垃圾邮件，大概 20 或 30 次，而且似乎只有重新启动才能解决问题。重新启动有点昂贵，因为它是 dom0。当我运行 archlinux 内核时这不是问题，但似乎对于 ubuntu 使用的任何内核都是一个问题。

有没有什么解决办法？我在网上搜索时，除了驱动程序源代码外，什么也找不到。

Megaraid SAS 设备：

01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)

我不确定还有什么有用的东西，它是一台 Dell Poweredge 2900 服务器，连接有 SATA 驱动器。

服务器运行良好，只是内核向日志中发送了过多的垃圾信息。

这仍在进行中，并且最近为与 2 个 CVE 相关的 RedHat 进行了修补：（清晰度）：此问题与 CVE 无关，相反，该补丁针对的是 2 个 CVE + 这个和几个错误修复。

（编辑）这似乎指向了这一点：https://lkml.org/lkml/2016/8/18/553

（编辑）我正在重新编译+测试内核，我会用补丁来托管它。

答案2

这是由驱动程序中的 megasas_get_pd_list() 函数发出的，请参阅 drivers/scsi/megaraid/megaraid_sas_base.c

    if (instance->ctrl_context && !instance->mask_interrupts)
            ret = megasas_issue_blocked_cmd(instance, cmd,
                    MFI_IO_TIMEOUT_SECS);
    else
            ret = megasas_issue_polled(instance, cmd);

    switch (ret) {
    case DCMD_FAILED:
            dev_info(&instance->pdev->dev, "MR_DCMD_PD_LIST_QUERY "
                    "failed/not supported by firmware\n");

            if (instance->ctrl_context)
                    megaraid_sas_kill_hba(instance);
            else
                    instance->pd_list_not_supported = 1;
            break;

....

我想知道将驱动程序内核参数 msix_disable 更改为 1 是否会改变行为。
