我的新笔记本电脑需要一分多钟才能加载 Fedora 38。我尝试了不同的内核，但根据我得到的引导加载统计数据，固件似乎是这里的问题。
我的笔记本电脑：HP 250 G9 7N034ES
运行以下命令后，systemd-analyze plot > /tmp/test.svg && xdg-open /tmp/test.svg我得到如下统计数据。
我还怀疑 Fedora 端可能有问题，因为 fwupd.service 也需要 20 秒才能加载
这是 dmesg 中的长部分的样子

编辑：如果我打开安全启动，并在 Fedora 上使用救援模式启动，那么速度会很快。否则对于其他所有情况都是相同的
答案1
它看起来fwupd.service是造成大部分延迟的原因。这是 Linux 的新的供应商中立系统，用于分发固件更新。
您可以尝试fwupdmgr get-devices查看它正在检测哪些具有可更新固件的设备，并fwupdmgr get-updates查看是否有可以应用的待处理固件更新。
您可能还想检查fwupdmgr get-history是否有特定设备的固件更新不断失败，如果是，请进一步调查，也许使用其他fwupdmgr子命令来禁用该特定更新。请参阅fwupdmgr --help | less获取更多信息。
