Re: Failed to emulate instruction sequence [ 41f646040874064c017d88eb144c89 ] at 0xbea5fcf9

Yes,I have also exchanged the bhyve binary. Now I'm trying to apply your
patch and then I will rebuild vmm.
I see that your code is :

[0xF6] = {
                /* XXX Group 3 extended opcode - not just TEST */
                .op_byte = 0xF6,
                .op_type = VIE_OP_TYPE_TEST,
                .op_flags = VIE_OP_F_IMM,
        },

but it seems wrong. Shouldn't be .op_flags = VIE_OP_F_IMM8 ?
