Since it is reproducible maybe not a networking hiccup. But maybe a hiccup of the PXE setup (thats why I asked for it). Or a hiccup of the quite complex shim loading if signed kernels are used. @Mike - in addition to my questions above could you use a non signed/shim load pattern as well to check

I agree that adding a dependency and pulling in python2 from the kernel seems very wrong. Per https://www.python.org/dev/peps/pep-0394/#recommendation I think the right header would be #!/usr/bin/env python3 That would be a (trivial) upstream change to the kernel as code is held there.

Hi, thanks for your feedback. We are at least much closer to what happened and thereby should be faster if it reoccurs. I don't think it is an interaction of the Kernel and Squashfs as we found that already initramfs unpack was broken. That is before Squash comes into play. I'll keep my test
