I had a look at this.  The hang is in our serial interrupt handling code -
we end up stuck in an interrupt loop as soon as we enable interrupts.
I didn't get very far with debugging it - on real hardware we ignore any
interrupts on other CPU's.  On qemu, that workaround doesn't work and when
we try to output a character on the console, we receive the constant stream
of interrupts [*].

However, if you start the VM with a graphical console, you can use 4 CPU's.

what happens!
