Gentoo LinuxがインストールされたThinkpad T400があります。 RAMサスペンドは魅力のように動作します。
ただし、ディスクの一時停止は機能しません。一時停止すると、ラップトップの電源が切れ、約30秒間ハードドライブにアクセスします。ところで、再びオンにすると正常にブートだけになり、前の状態に戻りません。
/var/log/pm-suspend.log一時停止前の様子は次のとおりです。

Sun Oct 21 15:26:08 CEST 2012: performing hibernate
ここで/var/log/syslog次の行を見つけました。
Oct 21 15:27:10 lenovo kernel: PM: Hibernation image not present or could not be loaded.
これは私のグラップ構成です。
title Gentoo Linux
root (hd0,0)
kernel /3.4.9-gentoo root=/dev/sda3 rootfstype=ext4 resume=swap:/dev/sda2 i915.modeset=1 fan_control=1
/dev/sda2私のスワップパーティションです。
何が間違っている可能性がありますか？
答え1
grub設定を変更してこの問題を解決しました。パラメータはswap:必須ではありませんresume。今私の設定は次のとおりです。
