 I tried a couple more things, which didn't really yield that much more.
 First, I built an MP debug kernel from the netbsd-7 branch. It also
 panics; however, the panic happens later. (It involves a locking issue
 with USB devices. If this is unrelated to everything else, I don't
 think anyone necessarily wants to chase new issues with 7.x.)
 
 To get around one of the predictable panics with -current, I commented
 out
 KASSERT(virq != 0);
 at line 561 of sys/arch/powerpc/pic/intr.c. This gives me a kernel that
 behaves the same as an MP non-debug -current kernel. That is, it
 freezes while devices are attaching, after the hard drives have been
 recognized. It doesn't seem to output anything significant that's
 different from the non-debug kernel.
