Manjaro 安装配置

停用 watchdog

关机时提示：watchdog: watchdog0: watchdog did not stop! 在台式机和笔记本上安装 Manjaro 时可以停用 watchdog 模块
Improving performance#Watchdogs

Many users need this feature due to their system’s mission-critical role (i.e. servers), or because of the lack of power reset (i.e. embedded devices). Thus, this feature is required for a good operation in some situations. On the other hand, normal users (i.e. desktop and laptop) do not need this feature and can disable it.

按照 archlinux wiki 上的方法，在启动参数中添加 nowatchdog 不能停用 watchdog

Note: Some users reported the nowatchdog parameter does not work as expected but they have successfully disabled the watchdog (at least the hardware one) by blacklisting the above-mentioned module.

另一种方法是在内核启动参数中添加 modprobe.blacklist=iTCO_wdt 来禁用 watchdog 模块。
编辑 /etc/default/grub 在 GRUB_CMDLINE_LINUX_DEFAULT 后添加 modprobe.blacklist=iTCO_wdt 保存退出后执行 sudo update-grub 来应用配置。

Edit /etc/default/grub and append modprobe.blacklist=iTCO_wdt to the GRUB_CMDLINE_LINUX_DEFAULT line
