boot hang under KVM Linux in kb8042
If I boot under KVM Linux (1:2.11+dfsg-1ubuntu7.12) and use the text console (non-EFI), it hangs
during bringing up the other CPUs. It seems like (though I can't be sure) the above thread
is stopping operation. We're in kb8042_send_and_wait() after we apparently received a key
that we then translated into needing a kb8042_setled(). I didn't press caps lock or anything...

I made sure to not touch the (emulated) PS/2 mouse or keyboard. This is via SPICE on virt-manager BTW.
We still see this apparent hang. So this seems like a spurious interrupt with scancode = 0x3a, (caps lock)
kb8042_process_key is seeing 0x1e.
