Higher load after update to 9.15

Troubleshooting
1

This is my first post here, so bear with me. Yesterday I updated from 9.12 (unsure) to 9.15 and noticed an increase of the load. System is running adguard, evcc and some smaller scripts. CPU is fine as well. Load is also ok, but has increased:

I noticed that

kworker/u21:0-brcmf_wq/mmc1:0001:1

consumed/is awak almost half the time the pi is up. Guess it’s related to wifi driver. Wifi has not changed since update. Any idea how to decrease load to previous level?

Kind Regards
