There are 2 problems here:
1.  Inability to wake application/auxiliary processors.
2.  Inability to send inter-processor interrupts.

The first probably does not cause a problem other than maybe
the calculation of cpu load. With only 1 CPU, it should not
be critical that IPIs cannot be sent, but since the kernel is
configured for SMP, it may send IPIs to itself, which also
don't work (the test IPI is one that's send to itself).

These two combined may be the cause the panic.

Try interrupting the boot in the FreeBSD loader (at the 9
second delay counter) and enter in order:
	set kern.smp.disabled=1
	boot -v

This hopefully disables SMP to the extend that IPIs are not
being used. See if that boots.
HTH,
