我用 Ryzen 3700x、MSI b450 主板和全新的 20.04 LTS 组装了我的新电脑。
我遇到了一些麻烦：有时恢复后 10 或 20 秒系统会冻结，硬盘指示灯亮起，网络指示灯亮起，但没有任何响应。没有 ping，没有 ctrl alt f。
有时内核崩溃，导致我的 btrfs / opt / vault 分区处于只读状态。我附上了 dmesg 内容

感谢你的帮助
我仍然遇到这个问题。当我大量使用文件系统时，问题就会立即出现。例如，当我在文件系统上运行 rsync 时
答案1
只需将其添加到您的启动参数中：
pci=assign-busses apicmaintimer idle=poll reboot=cold,hard
1. 如果使用 grub，请打开终端：
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=assign-busses apicmaintimer idle=poll reboot=cold,hard"
sudo update-grub
2. 如果使用 kernelstub（在 POP！OS 上），打开终端：
sudo kernelstub -a "pci=assign-busses apicmaintimer idle=poll reboot=cold,hard"
重启后，就不会再崩溃了！这个解决方案我复制自这里致谢归于该解决方案的原始发布者
