Can you explain how you get to the runtime callback paths from the
system reboot/shutdown handlers?

In any case, calling the plain _irq (rather than _irqsave) variants of
spinlocks when IRQs are already disabled is (another) bug. The plain
_irq variants are not permitted when IRQs have been previously
disabled.
