I was doing a trial run with just a few boards, it's a bit premature
to claim it's back. I didn't mean for the email to go out.

Looks like kernelci doesn't cover CONFIG_SMP=n boots, so I guess this
might be a new issue.

I haven't automated the new setup yet, so this was a one-off. I'll
bisect it over the weekend.
