i booted the kernel from my rp3440 on my j6000. i also get this cpu1 is
stuck message. putting a panic in the SMP C-code entrypoint is never
hit.

most oddly, putting a hpmc-causing insn sequence in the entry point
doesn't trigger either, so the cpu isn't coming out of the rendezvous.

even more oddly, the stwa insn in the bring up code looks fine.
