Kworker消耗了一个CPU核心的80%，如何一劳永逸地摆脱这个问题？

Question

每次我启动系统时，Kworker大约占CPU1的80%。

我试着按照这个答案中的解释来做。下面是grep . -r /sys/firmware/acpi/interrupts的输出：

我编辑了crontab，添加了这一行：@reboot echo disable > /sys/firmware/acpi/interrupts/gpe13和重新启动，这并没有解决问题。

在我只输入终端echo disable > /sys/firmware/acpi/interrupts/gpe13之后，CPU1负载减少到零，直到下一次重新启动或唤醒为止，一切都正常。解决这个问题的其他方法不为我工作。

是否有任何方法禁用gpe13或以某种方式一劳永逸地减少CPU负载？

Answer 1

只需将其添加到rc.local

键入sudo gedit /etc/rc.local并输入密码。

然后，在exit 0上面添加以下一行：echo disable > /sys/firmware/acpi/interrupts/gpe13并重新启动。

登录后，检查它是否已被cat /sys/firmware/acpi/interrupts/gpe13禁用。如果被禁用，它将返回类似于305 disabled unmasked的内容。
