This is the result of top command
I caught it at 99.7% but It even uses 170%. this is the output of journalctl
I thought it is something related to Bluetooth, so I turned it off but still got the same output. Cput usage rate gets lower, sound of cpu gets lower but then it starts again.


journalctl -fis there lots of output? I certainly seems like pulseaudio that is sitting at 123 minutes of cpu time is the culprit to me.journalctl -fhelped me, thanks. I found lots of messages there related totumblerd, some assertion check was failing. After killing tumblerd, the high cpu issue was resolved.
