hibernate的确很爽，但hibernate-ram不能用 ［已解决］

ProgramFan

今天安装了suspend2-sources,编译了内核，哈哈，加入了 lzf 的 hibernate 速度比 windows还快 。但美中不足的是不能suspend to ram ,hibernate-ram 在屏幕闪了下后就报错：

1. 
   
2. ***** ~# hibernate-ram
   
3. /bin/echo: 写入错误: 不允许的操作
   

复制代码

看了下hibernate-ram脚本，基本上用到echo都是 echo > /dev/null 。不知道为什么会失败。
麻烦大家帮忙看下。
大家有hibernate-ram不成功么？

原来是编译内核时要将 acpi --> sleep state 编译进去。
