Kaby Lake i5-7600K Crashing on Boot

Mytchel Hammond
Hello,

I've just replaced the cpu in my machine with a i5-7600k and openbsd
will no longer boot. The boot loader starts and loads the kernel which
runs until acpicpu is loaded which prints "Unknown opcode: 0018 @ 1cb4".
This happens on 6.4 and the latest snapshot but booting from the ram
disk works without a problem. This occurs on both bsd.sp and bsd (mp).
I've attached the dmesg from the ram disk but this doesn't show the problem.

I've taken photos of the trace and the dmesg from the crash.

trace:

https://ibb.co/7tXpFVf
https://ibb.co/j6DC8fn

dmesg:

https://ibb.co/6Df5x92
https://ibb.co/h8Sdg0B
https://ibb.co/xFvtGjt
https://ibb.co/hKDpwGY

The motherboard is a Asrock H110M-ITX/ac which has had the bios updated
to support kaby lake. It worked without any problems before with a
skylake pentium g4400.

Cheers, Mytchel.

I think you mentioned on IRC that you could get a complete boot with disabling
acpicpu. Could you run acpidump, tar up the output, and reply with that here?

Thanks.
