Hmm I'm beginning to understand what you say. Actually I didn't think
about initramfs that could launch
modules initcalls early.
It seems that modules initcalls are launched with the builtin
initcalls when one use initramfs.
Since I'm not using it, I see only the builtin initcalls before the
message of memory freeing.

I missed that point. And actually I misunderstood the real problem. My
issues with the graph happened
because of a bug in the bootgraph.pl script.
I have a patch ready that corrects it. I'm going to post it and
explain the real problem.

Thanks Alan!
