How can i fix it? I compiled from source, using OpenSUSE Tumbleweed with psi=1.
https://github.com/openSUSE/kernel-source/blob/master/config/x86_64/default

is there something which does prevent it?

Maybe you use mixed cgroup hierarchy. Could you provide cat /proc/self/cgroup?

cdown commented

oomd requires cgroup v2, but the hierarchy you're showing has resource control under cgroup v1.

You can enable tell systemd to use the new unified (v2) hierarchy, and simultaneously disable the old controllers with cgroup_no_v1=all on the kernel command line.

I'm gonna go ahead and close this one, I'm pretty sure the answer here is just to use cgroup v2, as required :-)
