AMD-VI：在空白 SSD 上安装 Arch Linux 失败后的完成等待循环

  • 772

更新 2019-05-21 19:37 EST：我的主板使用最新的 BIOS，发布于 2019-03-06，但仍然存在下面描述的安装问题。

更新：我将 Arch ISO 刻录到 CD，然后尝试从它启动，无论是 UEFI 还是旧版。相同类型的结果：

原始问题：我曾经dd将此Arch ISO（版本 2019.05.02）放在 U 盘上，然后尝试在我的台式计算机上从它启动。当 Arch 菜单出现时，我选择“Boot Arch Linux (x86_64)”。但是接下来是一堆错误消息，然后该过程就挂在那里无所事事。这是一张照片：在此处输入图像描述

The messages start off as "AMD-Vi: Completion-Wait loop timed out"

The messages include "kernel panic."

My motherboard is an MSI B450 Tomahawk with a Ryzen 5 2600 CPU. I've tried booting via UEFI and legacy with the same result.

How do I install Arch Linux?

    Linux Kernel With MSI B450

    The kernel fail in this case because of the support of the iommu feature; you can use some specific kernel adjustment (parameter) to fix your booting issue, this video demonstrate how to edit/apply the kernel parameters; here are some possibles solutions, try the different proposed parameters and choose the one that match best your needs. also you may turn off SVE in the bios.

    Possible Solutions: Kernel Parameters

    • iommu=off
    • iommu=off and amd_iommu=fullflush
    • amd_iommu=off
    • mem_encrypt=off
    • amdgpu.runpm=0
    • pci=noats

    Involved Technology Definition

    Kernel Parameters: (aka Boot Options) Kernel command line parameters are parameters that you pass on to the kernel during the boot process to adjust its features or capabilities.

    IOMMU: is a memory management unit that basically increase performance and security; additional details can be found here

    IOMMU State: on, off or fullflush (detail on the linked article)

    mem_encrypt: Add support for Secure Memory Encryption (SME). and defines the memory encryption mask that will be used in subsequent patches to mark pages as encrypted.

    amdgpu.runpm=0: disable the graphical power management in the linux kernel (it will be then handled at the hardware/firmware/bios level)

    pci=noats: disable PCI Address Translation Services

    Note

    Arch 启动盘：

    要将参数应用到启动盘，在启动菜单上，按“tab”以编辑启动命令，按空格（添加空格）然后写入参数，例如“iommu=off”，不带引号，然后按回车键启动

  2. Add acpi=off or iommu=soft while booting. Both have their disadvantages:

    iommu=soft:

    Linux can then detect everything properly (all cores) and I've had zero crashes. The only issue is that it's using software IOMMU which could have a performance penalty because it has to copy all the data of some PCI devices to sub 4G regions.

    acpi=off:

    Alternatively it boots with the kernel option "acpi=off" but only detects a single core/thread.

    To add one of these options, press Tab at the screen that says Press [Tab] to edit options and add it at the end of the line that contains initrd=.

    If that doesn't work, check and see if there are any available BIOS and/or Arch ISO updates. You might have a better chance of getting it to work if/when Arch includes Linux kernel 5 in their images.
