No, this was just an example from one of my gentoo systems.  It runs 
sys-apps/systemd-utils-259.3, but it does not have the warning you get 
in your log.

Well, I have the same here:

~ # grep -i qdisc -r /usr/lib/sysctl.d/
/usr/lib/sysctl.d/50-default.conf:-net.core.default_qdisc = fq_codel

Sorry, I don't know.  I was just comparing with what I get here and sys-
apps/systemd-utils does not seem to be the cause of it.  Unless it only 
goes into a tailspin with the default FIFO option?  :-/

FWIW, I also don't get your problem on another system which has 
NFT_FLOW_OFFLOAD [=n].
