Hello,

I don't have experience with Barrelfish, but after looking here[0], it 
seems that Barrelfish doesn't boot on another CPU than the first one 
(cpuid == 0):

875    // XXX: Only works from core 0 for now
876    assert(rck_get_coreid() == 0);

I think that your boot processor is not core 0 and that's why it 
crashes. I guess that you can remove this assert and then see what 
happens (i.e. make the OS boot).
