我的机器中安装了一个ITE8783看门狗芯片(OS Ubuntu 14.04.1).
@H_301_1@内核模块
it87支持.
@H_301_1@启动时未自动加载此模块.
@H_301_1@所以我把它添加到了/ etc / modules.现在模块在启动时加载.
it87: Found IT8783F chip at 0x290,revision 0 it87: Beeping is supported it87 it87.656: Detected broken BIOS defaults,disabling PWM interface
我已经认识到没有/ dev / watchdog设备出现.@H_301_1@所以我googled左右创建它做mknod / dev / watchdog c 10 130.
现在该设备出现但我认为看门狗过程不需要神奇地关注?@H_301_1@此外,是否有任何遗漏,因为/ dev / watchdog不是自动创建的?@H_301_1@我应该使用udev或其他任何东西创建设备吗?@H_301_1@我对内核模块,设备和监视器并不熟悉.所以请给我一个提示.谢谢!

原文链接:https://www.f2er.com/ubuntu/347850.htmlIf all else fails,and you have no hardware support,you can load the ‘softdog’ module to emulate some@H_301_1@ of the capabilities in software. However,this will provide greatly reduced protection as there is@H_301_1@ nothing to recover from a kernel panic,or a bad peripheral driver that blocks a software reboot.
基于此,我们可以得出结论,您的主板没有HW看门狗外设(或者内核没有为其插入适当的模块).
然后你可以回退到软件狗:
