Kworker consome ~ 80% de 1 núcleo da CPU, como se livrar disso de uma vez por todas?

Question

O Kworker ocupa cerca de 80% da CPU1 cada vez que eu inicializo o sistema.

Eu editei crontab adicionando esta linha: @reboot echo disable > /sys/firmware/acpi/interrupts/gpe13 e reiniciei, isso não resolveu o problema.

Depois que eu digito no terminal somente echo disable > /sys/firmware/acpi/interrupts/gpe13 , a carga da CPU1 é reduzida a zero e tudo está OK até a próxima reinicialização ou ativação. Outras formas de resolver este problema não funciona para mim.

Existe alguma maneira de desativar o gpe13 ou de alguma forma reduzir a carga da CPU uma vez por todas?

    

Answer 1

Basta adicioná-lo a rc.local

digite sudo gedit /etc/rc.local e digite sua senha.

Em seguida, acima de exit 0 , adicione esta linha: echo disable > /sys/firmware/acpi/interrupts/gpe13 e reinicialize.

Após o logon, verifique se está desabilitado com cat /sys/firmware/acpi/interrupts/gpe13 . Se estiver desabilitado, ele retornará algo como 305 disabled unmasked .
