Comment 28 for bug 1389077

I'm on 18.04, and saw huge cpu use all of a sudden by 4 tasks called kidle_inject running at 40% CPU each. I'm quite used to having this Thinkpad x230 tablet run hot since graphics e.g. for video don't seem to be accelerated. But in this case, the CPU and temperature as reported by psensor was not elevated before the kidle_inject processes went into overdrive. I'm not used to seeing them running normally.

I followed the advice at
 kidle_inject causing very high load - Ask Ubuntu
 https://askubuntu.com/questions/584636/kidle-inject-causing-very-high-load

to rmmod intel_powerclamp, and that killed the processes, but the temperature went up a bit, now to 100 degrees C, again despite low CPU load.

So something is going wrong here...
