Yes (on amd64, arm64 and armhf). I do not see the error in the systemd PID 1 except on an armhf kernel with CONFIG_BPF_JIT_ALWAYS_ON=y. But we do not need to consider the issue on the armhf kernel here. > If you remove "DefaultIPAccounting=yes" from user.conf, are the error > messages gone? Yes. This seems something like "Permission denied" or "Operation not permitted", but the error is "Invalid argument", which seems strange. Currently, to trigger this issue, I need task-xfce-desktop (on every arch.). I believe that this can be reproduced without task-xfce-desktop, and will try to find a reproduction procedure with CUI in a weekend... Best regards, Ryutaroh
