In the static alphanumerical context of /etc/modules.d/ the nf-conntrack modules getting loaded after sched-cake and causing the error output in syslog.
I.e., if it tries to load the qdisc before conntrack at boot, that will probably fail, but then it tries again later (when the qdisc is applied), and it succeeds?
The printed error might be inconsequential / begin in the greater scheme of things.
