我正在使用 debian sid，两年来我遇到了同样的问题。当我从 grub 启动时，我的系统屏幕上会显示以下文本：
Linux kernel in decompress level...Parsing elf
然后冷冻2-3分钟。在 dmesg 中我查看下一条消息：

当然，内核是不同的（3.2~3.16），但都来自 debian 存储库。另一个功能 - 如果我重新启动笔记本电脑（华硕 x52n），有 100% 的概率它可以快速启动而无需硬锁。有什么建议么？
同样的问题在这里http://forums.debian.net/viewtopic.php?f=5&t=117192（等待 160 秒并正常启动）
几年前我安装了 Debian stable，它没有这个问题。但有一个针对 sid 的测试。
