Ubuntu 16.04.1 slows down while idle – kidle processes
Warning: the below might make your CPU run hotter or overheat – use at your own risk!
A new Ubuntu 16.04.1 installation – after short usage the computer slows down and the CPUs are about 50% busy. There are some kidle_inject processes running which take this valuable CPU.
Top shows the following:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 6898 root -51 0 0 0 0 S 47.1 0.0 1:20.16 kidle_inject/5 6900 root -51 0 0 0 0 S 47.1 0.0 1:20.38 kidle_inject/7 6894 root -51 0 0 0 0 S 41.2 0.0 1:13.55 kidle_inject/1 6895 root -51 0 0 0 0 S 41.2 0.0 1:16.90 kidle_inject/2 6896 root -51 0 0 0 0 S 41.2 0.0 1:18.28 kidle_inject/3 6897 root -51 0 0 0 0 S 41.2 0.0 1:18.64 kidle_inject/4 6899 root -51 0 0 0 0 S 41.2 0.0 1:20.02 kidle_inject/6 6893 root -51 0 0 0 0 S 29.4 0.0 1:08.23 kidle_inject/0
To stop these processes run the following command – it will disable them only for the current session. I very rarely reboot so I haven’t looked into making it permanent yet.
$ sudo rmmod intel_powerclamp
