Ubuntu 18.04随机冻结

20

我已经在笔记本电脑Dell Inspiron 5000上安装了Ubuntu 18.04（AMD Ryzen 5 2500U / 8 GB RAM / 1 TB HDD / Windows 10 / 39.62厘米（15.6英寸）FHD / Vega 8图形） Inspiron 5575

即使有时没有应用程序，或者有时只有带有7-8个选项卡的Chrome操作系统，操作系统都随机冻结。我检查了内存占用量，还致电Dell支持中心。他们确认硬件没有问题。

另外，有关更多信息，我还有8 GB的空间和100GB的文件系统分区，其余空间用于备份或其他存储。

我需要确定并解决这个问题。

您是否尝试过内核引导选项的变体？在某些情况下，增加idle=nomwait生产线GRUB_CMDLINE_LINUX_DEFAULT（看起来应该像GRUB_CMDLINE_LINUX_DEFAULT="quiet splash idle=nomwait"）/etc/default/grub并update-grub确实对我有所帮助，至少对我的生活有所改善（Lenovo 720s / Ryzen 5 2500U w / Vega 8）。重新引导，检查dmesg引导参数（dmesg | grep -i idle-应该返回grub引导行）。

我在新PC AMD Ryzen上遇到了类似的问题。超级随机冻结，不可恢复。您的鼠标被冻结了吗？杜你有更新吗？

我的系统上有类似的问题。当我独自离开PC一段时间时，它将锁定在空闲状态。AMD Zen处理器上的C6深度空闲电源状态似乎是一个已知的错误。

我创建了一项服务，该服务在引导时会禁用此电源状态，并且该服务现在已经在我的系统上运行了几周，没有问题，因此我将其上载到OBS以供其他人使用。要安装它：

$ wget -nv -O - https://download.opensuse.org/repositories/home:jkist/xUbuntu_18.04/Release.key | sudo apt-key add -
$ sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/jkist/xUbuntu_18.04/ /' > /etc/apt/sources.list.d/home:jkist.list"
$ sudo apt-get update
$ sudo apt-get install amd-disable-c6

其他发行版本可以在这里找到

或者，您可以尝试在BIOS中禁用C6状态。但是，如果您的BIOS像我的一样笨拙，则可能没有该选项，或者可能必须禁用所有省电模式，而不仅仅是禁用C6状态。

看来，您有与我非常相似的问题。我的戴尔笔记本电脑上也有Ryzen处理器。但是，随机冻结不仅发生在空闲时，而且在我工作时也会冻结。顺便说一句，谢谢您的解决方案。我刚刚应用了它。让我们看看..
— 沙林·达沙迪亚
我安装了amd-disable-c6，但有时仍然冻结。您能进一步协助吗？
— 沙林·达沙迪亚
不幸的是，我不是戴尔笔记本电脑的专家。您正在使用哪个笔记本和发行版？我会尝试一些常见的步骤：1.确保将BIOS更新到最新版本（这对于Dell Inspiron尤为重要，在Google看来，坐姿似乎是一种常见的解决方案）。2.发生冻结时，通过进入tty（例如，按Ctrl + Alt + F2）检查它是否仅X冻结，然后查看是否可行。如果是这样，我将假定为图形驱动程序问题。3.如果这不是图形问题，请开始在BIOS中禁用CPU省电功能，然后查看有哪些问题。
— tumbleweed_user
常见问题是我的USB鼠标有时可以工作，但是我无法再打开窗口或关闭它们。有时整个系统会卡住。

我已禁用虚拟化和节能功能。在问题上没有成功。

我要尝试做的第一件事是确定您要处理的是内核还是硬件锁定（如果您已经尝试了这些步骤，则表示歉意）。

首先，启用内核崩溃转储服务。如果内核因段错误，软锁定或其他原因而出现紧急情况，这会将文件粘贴在/ var / crash中：https : //help.ubuntu.com/lts/serverguide/kernel-crash-dump.html.en

如果是硬件锁定，并且Dell扫描未发现任何东西，这可能是诊断的噩梦。CPU温度可能是一个因素。您可以安装和使用lm-sensors软件包，并使用sensors-detect和sensors命令获取各种外围设备的温度。

其他问题可能是由芯片组错误引起的，如果您尚未这样做，通常可以通过更新BIOS来解决。

您可以做的其他事情是使用smartmontools软件包检查HDD。这将告诉您驱动器是否状况不良：https : //help.ubuntu.com/community/Smartmontools。

最后，您检查了记忆吗？GRUB引导菜单中通常有一个memtest选项，因此运行它。

根据错误，驱动器看起来可疑。但是，我要做的第一件事就是修复您的内核错误。根据这篇文章，IOAPIC错误可能导致不稳定，因此这是首先要考虑的问题。superuser.com/questions/1052023/ioapic0-not-in-ivrs-table

谢谢，我将在此方面做进一步的工作，并告诉您。

另一件事是，硬盘上有一些坏扇区，但是由于频繁冻结，唯一的方法是硬重启。因此，可能是造成这种情况的原因。当前已安装了两个版本的内核。如何删除一个？

您的SMART数据显示大量不可纠正的错误。在这种情况下，系统冻结并不奇怪。我真诚地怀疑这实际上是随机的。我要做的第一件事是备份所有关键数据（根据您的GSmartControl屏幕截图，某些数据可能已经从您的Seagate Hard Drive中丢失了）。然后更换驱动器。尝试纠正在有故障的硬件上运行的操作系统错误，就像在沙子上建造城堡一样。需要可靠的基础。

这些错误是由于频繁冻结而产生的。我每次都必须强制重启。没有其他选择。
— 沙林·达沙迪亚
@SaurinDashadia SMART错误不是由系统冻结引起的，反之亦然。
— 极客长老
我认为，由于频繁冻结，导致我强制重新启动系统，并且强制重新启动可能是出现不可恢复的错误或坏扇区的原因。
— Saurin Dashadia
@SaurinDashadia在我30多年的经验中，强制重启系统从来不是造成媒体故障的根本原因。典型的罪魁祸首包括温度过高，狡猾的布线和过大的冲击，老年..

自16.04之后更新（或实际安装）18.04之后，我遇到了同样的问题。问题是，首先，我在管理Nvidia驱动程序时遇到很多麻烦（K2100M是真正的麻烦制造者）。因此，即使在观看电影，编码或关闭笔记本电脑时，我也会出现随机崩溃的情况。我最近通过以下方式将内核更新为15.0.0.25-generic

sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

从那时起，我完全没有随机崩溃的问题。您也可以查看我的文章。

我已经尝试过了。让我们期盼最好的结果。
— 沙林·达沙迪亚
怎么样了 到目前为止有没有崩溃？我发现，回到旧内核之后，如果我最大化Visual Studio代码，一切都会崩溃。但是现在不行了，一切正常。

它尚未解决问题。昨天晚上发生了。但是，今天没有这样的迹象。让我们再等几天。

在5.0.0-25-generic带有Ryzen 5 3600 CPU和Nvidia RTX 2060的全新安装的系统（内核版本）上，我也遇到此问题。安装amd-disable-c6或HWE程序包无济于事，但安装nvidia驱动程序确实有所帮助。这是我的方法：

  • 将以下行添加到 /etc/modprobe.d/nvidia-graphics-drivers.conf
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off
  • 添加nomodeset到文件中的GRUB_CMDLINE_LINUX_DEFAULT变量，/etc/default/grub因此如下所示：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
  • 跑 sudo update-grub
  • 重启
  • 添加PPA存储库：
sudo add-apt-repository ppa:graphics-drivers/ppa
  • 通过键入切换到运行级别3 sudo init 3。如果在切换到tty / 1后看到黑屏，请使用CTRL+ALT+F1
  • 安装驱动程序
sudo apt-get install nvidia-driver-430
  • 重启

在那之后，我没有任何冻结。

这也可以在配备RTX 2060的HP Omen上为我解决，而无需尝试任何其他解决方案。到现在已经一周了，几乎每天都冻结之后，再也没有冻结了。

@ diogen737我有Raven Ridge [Radeon Vega系列/ Radeon Vega移动系列]图形。
— 沙林·达沙迪亚
非常重要的是，一旦完成，我必须删除nomodeset并再次运行update-grub以恢复屏幕分辨率。通过放置nomodeset，您不会运行视频驱动程序。黑名单nouveau将nvidia的开源图形版本列入黑名单。您还可以通过GUI从软件更新程序> settings＆livepatch>常规驱动程序安装驱动程序

我遇到了同样的问题。我们的服务台能够通过更新Nvidia驱动程序来对其进行修复。显然，开放源代码有时会出现问题。

我在两个系统和两个不同版本的Ubuntu（16.04和18.04）上遇到了此问题。我无法在第一个系统上解决该问题，但是在我的18.04设置中找到了修复程序。

它的缺点是；
如果您在中options nvidia_drm modeset=1设置，/etc/modprobe.d/zz-nvidia-modeset.conf
则删除该行或整个文件（如果该行已全部删除）。（这是为了解决页面撕裂而添加的，但是对此我有更好的解决方案，请参阅稍后）。

背景
在ubuntu 16.04上，我经常冻结。我尝试了升级和降级内核，设置了不同的C状态，尝试了各种不同的设置GRUB_CMDLINE_LINUX_DEFAULT，对BIOS设置进行了许多调整，启用/禁用了chrome中的GPU渲染，各种不同的nvidia驱动程序/配置.....
这些都不是解决了这个问题。（旁注；尝试超频CPU会使问题更加严重，即使它在Windows下经受了数小时的稳定测试）。

然后，我重建了机器（新的CPU和主板，其他所有东西都保持不变），然后升至18.04。在这个新设备上，我将CPU超频至5.2GHz，并享受非常稳定的非冻结OS（正常运行时间长达几个月！）。我唯一的问题是全屏观看Netflix时页面撕裂。在试图解决这个我试过一个建议（从这个职位它是增加）options nvidia_drm modeset=1对/etc/modprobe.d/zz-nvidia-modeset.conf。 这导致了可怕的冻结问题再次出现。再次取出该文件恢复了我的操作系统的稳定性。

因此，现在我可以拥有超频的CPU，并在chrome中启用了硬件加速渲染，并且无需对C状态或grub配置进行任何更改。
解决页面撕裂的更好解决方案是在nvidia X服务器设置中启用“ Force Composition Pipeline”和“ Force Full Composition Pipeline”。

我不知道options nvidia_drm modeset=1从/etc/modprobe.d/zz-nvidia-modeset.conf其他人那里删除是否会是解决方案，但是如果这样做可以节省我浪费时间来解决此冻结问题的时间，那么我会很高兴的！
