In my /usr/src/linux/Makefile, I remembered to set SMP = 0, but when it
still compiled with __SMP__, I commented it out, and it went away, and I
was happy. I suspect that that may be my problem, but nonetheless I shall
enthrall you all with the gory details. =)
It also seemed to be spending a lot of time at 0xc01084bf in hard_idle():
