Thanks for the ping. The build should run once the GitHub app is installed.

Maybe it is enough to retry with the latest kernel. The latest error I see here is not related to restartable sequences and the files which are running in the test containers are using binaries from glibc 2.31 (busybox) and glibc 2.28 (debian).

At this point, with the latest kernel, it might just work.

Rebased.
I guess the criu stuff can be revisited in a separate PR later.

We have a 6.x Kernel on the roadmap, but it's a significant amount of labour and iteration to take a Firecracker guest Kernel and only enable the specific features for containers and ebpf, so if that resolves the issues with CRIU we will reach out when it's ready.

I'd suggest you merge this PR and skip those tests for the time being on arm64. The project's test coverage on native hardware will be in a much better position already. Would you agree?
