我有一个问题，但无法找到答案(很容易)。在我的 Ubuntu 安装中，一个 kworker 线程消耗了 100% 的 CPU，这导致我的计算机有时非常慢或崩溃。

最佳答案

如果运行命令:

grep . -r /sys/firmware/acpi/interrupts/

并检查是否有任何高值，例如:

/sys/firmware/acpi/interrupts/sci:     264
/sys/firmware/acpi/interrupts/error:       0
/sys/firmware/acpi/interrupts/gpe00:     264   enabled
/sys/firmware/acpi/interrupts/gpe01:       0   invalid
...
/sys/firmware/acpi/interrupts/gpe1F:       0   invalid
/sys/firmware/acpi/interrupts/sci_not:       0
/sys/firmware/acpi/interrupts/ff_pmtimer:       0   invalid
/sys/firmware/acpi/interrupts/ff_rt_clk:       0   disabled
/sys/firmware/acpi/interrupts/gpe_all:     265
/sys/firmware/acpi/interrupts/ff_gbl_lock:       0   enabled
/sys/firmware/acpi/interrupts/ff_pwr_btn:       0   enabled
/sys/firmware/acpi/interrupts/ff_slp_btn:       0   invalid

备份你的文件

cp /sys/firmware/acpi/interrupts/gpe00 /root/gpe00.backup

并简单地禁用它:

echo "disable" > /sys/firmware/acpi/interrupts/gpe00
