在过去的几个月里，我的 Linux 安装每隔几个小时左右就会出现内核恐慌。那时我并没有太困扰，因为我在另一个驱动器上安装了 Windows，由于 Linux 上不断崩溃，我最终使用 24/7 .

我刚开始使用 Arch Linux 时使用的是内核版本 5.11 到 5.12 左右，我记不太清了。令人沮丧的几周后，我切换到了 Gentoo Linux，但随着内核恐慌越来越频繁，情况变得更糟。几个月后我切换回 Arch Linux，它仍然出现内核恐慌，但不那么频繁了。

我没有第一次安装 Arch 的系统日志，但我记得这主要是由 Firefox 或 Discord 引起的。我确实有一些来自 Gentoo 的日志，据我所知，它通常是 Discord 崩溃、段错误和内核 NULL 指针取消引用。在我当前的 Arch 安装中，firefox 上有很多转储的核心和我无法理解的内核崩溃。

在 5.10 之前我从来没有发生过任何崩溃，我不知道导致这些崩溃的 firefox、discord 或内核是否发生了变化，或者我的硬件是否有故障，我怀疑这是因为 Windows 一直运行良好。我总是在 Gentoo 和 Arch 上使用最新的、最前沿的内核。我曾在 Gentoo 上试用过 Zen 内核，但得到了相同的结果。Firefox 上是否有某种设置可以解决此问题，或者我应该尝试与 AUR 不同的内核，如 linux-hardened、linux-lts 或 linux-zen？

编辑：当我输入这个时，一切都变得疯狂。据我所知，这是一个每 0.001 秒发送一次垃圾邮件的错误，创建了一个大约 1.6 GB 的日志文件。什么？

这些崩溃最糟糕的是，我什至无法通过按住电源按钮来关闭我的电脑。就像硬件级别的整个系统完全冻结一样。我真的需要关闭电源才能将其关闭。

硬件：Ryzen 5 3600X、16GB RAM、GTX 1660 Ti、Linux M.2 SSD、Windows 硬盘。

其他系统日志：

我只是在一切再次崩溃之前将整个日志转储到谷歌驱动器中。

我按照本指南安装了 Gentoo +systemd+KDE。在 gentoo 中启动后，我注意到一个不寻常的行为。

  • 启动后，我可以启动应用程序，前提是没有使用 WiFi 连接。

  • 一旦连接到任何 WiFi 网络，KDE 应用程序将拒绝启动。

  • 现在，即使我断开 WiFi 连接，我也无法从菜单中启动任何应用程序。

从菜单中单击任何应用程序后，它会立即出现蓝色旋转圆圈，然后消失 KDE 5 vlc loading

我注意到的另一件事

  • 连接到 WiFi 后，KDE 出现登录屏幕错误，否则不会发生

我怎么解决这个问题？如果需要任何输出，请随时询问！并提前感谢您的帮助！

我习惯了 debian/raspbian，设置计算机的主机名很简单：

/etc/hostname:

my-computer

和

/etc/hosts:

127.0.0.1   localhost
::1     localhost ip6-localhost ip6-loopback
ff02::1     ip6-allnodes
ff02::2     ip6-allrouters

127.0.1.1   my-computer

在这些更改和重新启动之后，我可以ssh [email protected]从本地网络上的任何其他机器上。

我很难在新的 gentoo 系统上获得这种行为。我已经尝试了 gentoo 论坛上 2-3 岁帖子中的其他一些设置，但没有运气。

我在虚拟上安装了一个新的 Gentoo 服务器，带有虚拟局域网接口。从 live CD 启动时，网络 (eth0) 可用。启动到新创建的系统时，启动时网络丢失。界面显示在 dmesg 中。中ifconfig，eth0缺失。

怎么了？

我有一台装有 gentoo 的机器，它无法访问互联网，但我想在上面安装一些软件包。我没有另一台机器用gentoo，怎么下载包呢？谷歌告诉我你使用emerge在一台机器上下载并在另一台机器上安装，但正如我所说，我有一台gentoo机器，如何用另一个操作系统（windows或ubuntu）下载包？

我正在使用Gentoo，需要安装更新版本gcc的.

我想做相当于apt-get install gcc=8.0.3-r1但不知道怎么做。它甚至不需要是版本 8 - 任何 4.8 或更高版本都可以。

我试过的：

emerge =sys-devel/gcc-8.0.3返回there are no ebuilds to satisfy "=sys-devel/gcc-8.0.3".

emerge-webrsync返回command not found。eix-sync似乎成功完成，但eix sys-devel/gcc只返回最高 4.7 的版本。我希望其中一个等同于，apt-get update但看起来并非如此。

我究竟做错了什么？

我在主板上安装了三星 SSD 970 EVO Plus NVMe M.2 500GB，它工作正常，但是当我打开例如gnome-disks或parted以获取有关磁盘的更多信息时，系统无法识别磁盘的型号。SMART 数据和自检也被禁用。

这只发生在 M.2 磁盘上。普通 SSD 工作正常。

是否有任何内核选项或系统配置会导致这种情况？

我有linux-4.19.44-gentoo内核。

Distro: Gentoo
systemd: 242

有一段时间，在我在这里的两个系统上，我一直无法正确关机（停止、关机、重启）。它通过关闭服务等来完成大部分工作，然后就停止了。我必须使用神奇的 SysRq 键来完成这项工作。

我终于启用了 debug-shell.service 并看了一下。事实证明，systemd 在某个时候会挂在 100% CPU 上。通常有 1 或 2 个服务仍然有进程，其中一些是僵尸（我假设因为 systemd 通常会删除它们但不工作）。

这就是我所能确定的一切。我还能做些什么来诊断问题？

编辑：示例截图（裁剪）：https ://imgur.com/OVOozrI内容实际上差异很大，因为事情的顺序可能不同。

编辑 2：syslog 的相关部分。我觉得那里没什么有趣的。唯一没有“停止”而“停止”的是Dovecot。但是，您可以在底部看到，它最终确实退出了。这似乎是在 systemd 开始挂起之前。我记得在调试 shell 中，Dovecot 是一个僵尸。就在不久前，我尝试关闭 Dovecot（成功）然后重新启动，但 systemd 仍然挂起。
