私の新しいノートブックからFedora 38をロードするのに1分以上かかります。別のカーネルを試してみましたが、取得したブートロード統計によると、ここではファームウェアが問題のようです。
私のラップトップ：HP 250 G9 7N034ES
次のコマンドを実行すると、systemd-analyze plot > /tmp/test.svg && xdg-open /tmp/test.svg次の統計が得られます。
また、fwupd.serviceもロードするのに20秒かかるので、Fedora側に問題があると思います。
これがdmesgで長い部分が見える様子です

これfwupd.serviceはほとんどの遅延を引き起こすようです。これは、ファームウェアアップデートを展開するためのLinuxの新しいベンダーニュートラルシステムです。
fwupdmgr get-devicesアップデート可能なファームウェアとして検出されたデバイスを確認し、fwupdmgr get-updates適用できる保留中のファームウェアアップデートがあることを確認できます。
fwupdmgr get-historyファームウェアアップデートが失敗し続ける特定のデバイスがあることを確認し、その場合はさらに調査し、他のサブfwupdmgrコマンドを使用してその特定のアップデートを無効にすることもできます。詳細についてはを参照してくださいfwupdmgr --help | less。
