So you're now rebooting with the secondary CPUs still running. I guess
that the secondary CPUs end up crashing and don't restart.
I think more the question is why the CP15 cache clean/flush is hanging
with the other CPUs taken down. All the other CPUs will be doing is
sitting in a loop doing nothing.
