我有一台安装了 Gentoo Linux 的 Thinkpad T400。挂起到 RAM 的作用就像一个魅力。
但是，暂停到磁盘不起作用：如果我暂停，笔记本电脑会关闭电源并访问硬盘大约 30 秒。但是，如果我重新打开它，它只会正常启动，但不会恢复到之前的状态。
这是/var/log/pm-suspend.log暂停之前的情况：

Sun Oct 21 15:26:08 CEST 2012: performing hibernate
在/var/log/syslog我发现以下行：
Oct 21 15:27:10 lenovo kernel: PM: Hibernation image not present or could not be loaded.
这是我的 grub 配置：
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是我的交换分区。
可能出什么问题了？
答案1
我通过更改 grub 配置解决了这个问题。参数swap:中的不需要resume。我的配置现在看起来像这样：
title Gentoo Linux
root (hd0,0)
kernel /3.4.9-gentoo root=/dev/sda3 rootfstype=ext4 resume=/dev/sda2 i915.modeset=1 fan_control=1
