Uhm that's a strange one, I cannot get a machine like that..
The closest is a 16 CPUs where I can limit the resources in vng.

Well whenever I pass some argument to vng (instead of just vng -v that brings
up an interactive shell), I see an unrelated lockdep splat in
timekeeping_init(), but all clear when the KUnit runs..

I'm going to try and understand better what's going on, I don't think I can
reproduce it easily.

Thanks,
Gabriele
