Hi! I’m having the same issue, roughly around the same HA version (it started when I updated from 2021.12.10 to 2022.2.9), running on RPi 3 under HAOS.
In both your profiles and on mine I can see an extremely high amount of time spent on method 'poll' of 'select.epoll' objects (in my case, 95% of the time). Would that be a clue? I haven’t seen it mentioned anywhere else. From a extremely quick web search, that seems to be the stacktrace when the Python interpreter is reading data from an external program. I’m not sure about that, though.
Oh, and thanks for sharing the commandline you used. That was helpful to me.
