Should 11.2-p4+bhyve be able to run 12.0-ALPHA8-amd64 ?

On a 11.2-p4 host, trying to run 12.0-ALPHA8-amd64 under bhyve.

Right after console emits:

	FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
	FreeBSD/SMP: 4 package(s) x 1 core(s)
	arc4random: no preloaded entropy cache

Bhyve quits with:

	Failed to emulate instruction [0x0f 0xae 0x3b 0x8b 0x04 0x25 0xf8 0x5d 0xb8 0x81 0x48 0x01 0xc3 0x4c 0x39] at 0xffffffff8104abb0
	Abort trap


According to a disassembler "0f ae 3b" is "clflush byte ptr [%rbx]"

Never attribute to malice what can adequately be explained by incompetence.
