I was wrong earlier. Since checkpoint-restore/criu#2642 is closed (2 days ago), we use the same criu version (4.1) on Ubuntu 24.04 (amd64) and Ubuntu 22.04 (arm64), and it has not failed in there (yet?).

We also run CI on Fedora 41 (which has criu 4.0) and AlmaLinux 9 (criu 3.19), those are not failing. If repositories are provided, I can try running criu 4.1 on these two (AL9 and F41).

criu 4.1 on F41 is not failing like this, instead it's failing in another way (checkpoint-restore/criu#2650). Meaning, this issue is probably specific to older kernels.
