 The halt button on 3MIN and 3MAX+ systems is an ordinary I/O ASIC
interrupt which can get masked and also needs a working handler to have
any effect at all.  Thus e.g. if a kernel locks up with interrupts masked
in the CPU, the halt button won't recover -- a reset, i.e. effectively a
power cycle is required.
