Ubuntu 在华为 Matebook D (Ryzen 5 2500u) 上不断崩溃

我在这里看到了一些关于 Matebook D 的帖子，并尝试了几种解决方案，但到目前为止似乎都没有奏效。我正在运行 Ubuntu 19.04（一周前还是 18.04）。我已将内核更新到 5.3.7。通过我的 Windows 分区，我确保 BIOS 已更新（我相信是 1.22）。我仍然发现在 Chromium 浏览器上它会在 1 分钟到 1 天内冻结。这种情况似乎更常发生在 JS 密集型网站上，这些网站涉及大量内容的自动加载，例如 Facebook。在日志中我得到了：

09:49:50 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)

有人能建议我该怎么做才能阻止这种情况发生吗？如果我需要提供更多信息，请告诉我

答案1

看来 ryzen 处理器的 IOMMU 存在大量问题。我也遇到过这种情况。尝试在 /etc/default/grub 的 GRUB_CMDLINE_LINUX_DEFAULT 行中添加以下选项：

iommu=soft

然后运行

$> sudo update-grub

最后重启

答案2

尝试向内核启动选项添加如下内容：

processor.max_cstate=1 // or 5
