我在戴尔笔记本电脑上使用的是ubuntu 15.10。它工作得很好，但最近我的启动时间很慢(~1分钟)。所以我环顾四周，当我读取/var/log/boot.log文件时，我看到了以下错误：

[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.

所有其他服务(tftpd除外)都在完美地运行。以下是完整的输出：

下面是systemctl status systemd-modules-load.service的输出：

错误到底是什么，它会影响我的启动时间吗?应该如何修复呢？

什么是“未能启动加载内核模块”?

Systemd读取目录/etc/modules-load.d中的文件，以便加载此服务的模块。如果这些文件中指定的模块不存在于启动内核的/lib/modules目录中，则会出现“启动加载内核模块失败”的错误。下面是来自/etc/modules-load.d目录ls -lA的内容

-rw-r--r-- 1 root root 119 Apr 20 17:01 cups-filters.conf
lrwxrwxrwx 1 root root  10 May 12 10:39 modules.conf -> ../modules

从`journalctl`

获取详细信息

在我的例子中，下面是journalctl的相关部分：

May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'lp'
May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'ppdev'
May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'parport_pc'

如果您执行journalctl | grep modules，您将看到哪些未能加载

在我的例子中，/etc/modules (由符号链接指向)是空的，但是cups-filters.conf文件包含对抛出错误的模块的引用：

# Parallel printer driver modules loading for cups
# LOAD_LP_MODULE was 'yes' in /etc/default/cups
lp
ppdev
parport_pc

使消息消失

我的笔记本电脑甚至没有任何并行端口，这并不奇怪，所以我不需要那些模块。无论如何，它们不能加载，因为它们不在/lib/modules/$(uname -r)中

我注释掉了这三行(将#放在每个模块名称前面的行的开头)，错误消息就消失了。

不过，我没有注意到启动时间有什么不同。

检查journalctl以查看哪些模块未能加载
阅读/etc/modules-load.d中的文件以查找对这些模块的引用
注释掉指定这些模块以使错误消失的行(但在编辑之前请制作备份副本)。
重新启动，看看这对启动时间是否有任何影响。
