Unifi USG-3P Cavium CN5020

[Joel <joelp%sdf.org@localhost>]

Hello -- realizing that 1) I have no use for my old Unifi USG-3P, 2) I 
have never tried NetBSD on a MIPS device, I decided to give NetBSD-10 a 
try on it.

Booting with NetBSD-10 RELEASE was pretty straightforward using the 
octeon.img on a USB stick (replacing existing). Here's my bootcmd:
    bootcmd=fatload usb 0 $loadaddr netbsd;bootoctlinux root=dk1a

Cool.

But I noticed this in dmesg:
    [   1.0000000] cpu1 at cpunode0 core 1: disabled (uniprocessor kernel)

So I built a new kernel using OCTEON as the base and added:
    options     MULTIPROCESSOR

Now I see this in dmesg:
    [     1.000000] cpu1 at cpunode0 core 1 disabled (unresponsive)

Is there another option needed in the kernel config?
Is multiprocessor even supported on evbmips octeon?

Full dmesg (with generic uniprocessor kernel) below.

Thanks -- Joel
