I'll try your config later, though in a different environment. If I'm
unable to reproduce, I'll provide further instrumentation suggestions.
Gilles instrumentation confirmed that the CPU is taking a standard
external IRQ (#23: 0x37-FIRST_EXTERNAL_VECTOR). I suspect we are
enabling hardware IRQs too early during the boot of secondary CPUs,
causing this BUG as not all data structures are initialized yet. What
enables then can be some code that we do not run normally, on x86-64 or
maybe also x86-32 unless using your .config and/or your hardware.
