Where exactly did you get this kernel, do you have a URL reference?

That sounds great.

The way to prove this is to put an instrumented kernel on penalosa.
I think the way forward is:
* You get me a console trace.
* I give you an instrumented kernel/initrd.
Are you allowed to boot a kernel/initrd that I send you?
