从我的内核消息中：
126.016 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x16 link at 0000:16:00.0 (capable of 252.048 Gb/s with 16.0 GT/s PCIe x16 link)
我的Supermicro X11-SRM-F只有一个 x16 PCIe 3.0 插槽，供 nVidia RTX 3070 使用。
是什么将其限制在 8GT/s 而不是 16GT/s 的速度？
Ubuntu : 20.10
内核：5.8.0-43-generic
显卡：英伟达 GTX 3070
更新：我的另一台 PC（核心 i5 Haswell）有更严格的限制：
pci 0000:01:00.0: 32.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s PCIe x16 link at 0000:00:01.0 (capable of 126.016 Gb/s with 8.0 GT/s PCIe x16 link)
当您在计算机完全关闭之前关闭计算机时，您可能会看到大量 PCIE 错误消息快速滚动几秒钟。如何在新安装的 Ubuntu 19.10 上重新启动/关闭后修复滚动 PCIE 错误？
我最近购买了一台戴尔 Precision 7530 笔记本电脑，它在 500GB SATA 驱动器上预装了 Ubuntu 16.04。后来我买了一个 1TB M2 PCIe NVMe SSD，除了原来的 SATA 驱动器外，还安装在空闲插槽中。
然后我在新的 SSD 驱动器上安装了 Ubuntu 19.10。但是，这不起作用，请参阅我的上一个问题。
后来，我尝试物理移除 SATA 驱动器，然后它在 M2 PCIe SSD 上正常启动到 Ubuntu 19.10。现在我认为问题已经解决了，我从同一品牌购买了一个新的 2TB M2 PCIe SSD 。我移除了 1TB SSD 并用 2TB SSD 替换它，然后安装了 Ubuntu 19.10（来自 USB）：
但是，当我重新启动计算机时，我得到“找不到可启动设备。”：
按 F2 我进入了 BIOS：
这表明该磁盘以“M.2 PCIe SSD-0”的形式存在。我觉得很奇怪 1TB SSD 可以正常启动，而 2TB SSD 不能启动。
任何想法可能是什么问题？
尝试安装 ubuntu 18.04.3 时
我认为主存储是SSD连接的M2接口。
编辑：安装失败，崩溃报告器也挂起。当我取消报告对话框时，我被指示只读命令行日志
我在 Acer Swift 上安装了 Lubuntu - 将它安装在 SSD 上已经需要将控制器的 BIOS 设置更改为 AHCI。
现在我坚持让关机正常工作。/etc/default/grub我已经尝试了一些选项
reboot=biosacpi=force apm=power_offpci=nomsi,noaer（我知道这应该只关闭错误消息）我在关机时遇到的错误是：
PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)
device [10de:id13] error status/mask=00100000/00000000
[20] UnsupReq (First)
TLP Header: 40000008 000000ff a024c010 f7f7f7f7
显示该错误后，没有任何反应，并且无法正常关闭。
我还没有安装额外的 SATA - 我想在修复关机后做......

我最近在我的 PC 上将 Ubuntu 16.04 升级到 18.04（使用 Nvidia GeForce GTX 1080 Ti GPU），自从我的文件系统是从这些巨大的日志文件中建立起来的。每次我关闭我的电脑时，我都会收到无数的 pcieport 消息，直到电脑自行关闭。
昨天我把我的机器开着过夜，当我回到它时，有一个通知说磁盘空间已全部用完，即/dev/sda1100% 使用。我设法通过du-command 找到了这一点，并将问题定位到/var/log/-folder 中的日志文件，其中包含超过350GB.
目前，日志文件正在重新构建，现在它们占用的空间大约为150GB. 导致问题的日志文件是：syslog.1, syslog和kern.log
我的问题是：是什么导致了这个问题以及如何解决它？
我在下面列出了有关我的系统的信息和日志文件中的几行。我将再次删除它们，但无休止地删除它们似乎不是最好的长期解决方案。

我有一台华硕笔记本电脑，我最近切换到了 linux (kubuntu 18.04)——顺便说一句，我很喜欢它！
我的问题是我的操作系统应该很好地支持哪个半 pcie wifi 适配器（以获得 5ghz 并从我的 400mbps 连接中获得尽可能多的东西）？我不想花太多钱。我已经尝试过 USB 适配器选项，但是当迷你 USB 放在我的包里时，我一直在破坏它们，而带有天线的那些只是烦人！
提前感谢您，如果有任何信息丢失，我们深表歉意！
PS：有人可以评论并告诉我是否可以在该插槽中添加任何半 pci-e 卡吗？

我最近决定在我的个人笔记本电脑上切换到 Ubuntu。我决定安装 Ubuntu 16.04，因为我遇到了 18.04 版本的问题。两天后，我能够在我的机器上正确安装。
我必须在启动时在控制台中添加参数"pci=noaer"，squash以克服启动时的错误（PCIe 总线错误）。
之后，我就可以使用并连接到互联网了。两个小时后，互联网停止工作。我已经尝试了一切，但我一无所获。
我的网络适配器是 RTL8821AE 802.11ac PCIe 无线网络适配器。我拥有一台华硕机器，我完全删除了 Windows，所以我只安装了 Ubuntu 16.04。任何帮助将不胜感激。
我尝试更新依赖项，使用设置，但没有解决我的问题。老实说，我即将辞职。

也试试 sudo aptitude safe-upgrade -y，也没有解决问题。
我在 HP 笔记本电脑上安装 Ubuntu 时遇到问题。它曾经给出一些与和平总线相关的错误。
我不明白这个错误，但在访问了许多网站后，我找到了解决方案。
该解决方案要求我在启动时向内核添加一个参数“pci=nomsi” 。
然后通过更新“”使其永久化/etc/default/grub。
我尝试了这个解决方案，效果很好。
但我想知道，什么是 pci 总线，该命令是什么意思？
我从 StarTech 购买了 PCIe USB 卡 PEXUSB3S44V（链接如下）。我使用 ubuntu 16.04 和内核 4.15。输入 lspci 和 lsusb 时我可以看到卡片。但它不起作用。我联系了 StarTech 支持，他们告诉我这张卡不适用于高于 4.9 的内核。我有什么办法解决这个问题吗？我可以编译和运行内核 4.9 吗？这会干扰这个系统上的其他软件吗？我只在这个系统上使用 CUDA 和 tensorflow。
