      I have Ubuntu 16.04 installed on Redmi 3S.

      Distributor ID: Ubuntu
Description:    Ubuntu 16.04.7 LTS
Release:        16.04
Codename:       xenial

      When I run top via ssh, I see that the CPU usage is relatively high, around 17-30%.

      When I plug in a USB keyboard, CPU usage becomes normal.

      I have noticed that when no USB keyboard is connected and CPU usage is high, the repowerd.log file in /var/log grows rapidly. It looks like repowerd is in a loop and is logging data multiple times per second.

      When I plug in a keyboard, the repowerd.log stops growing and the items in that log look normal.

      Also, if I stop the repowerd daemon, the CPU usage goes to normal.

      What could be the problem?
