Install a single CPU kernel by hand on the dual board. The vendor is reporting a
dual CPU system when there is single CPU which is a bit iffy.  The 'noapic' boot
option should also work

Newer kernels are smarter about this brokenness and act defensively. Only just
noticed the old unclosed bug still around
