Well, this doesn't help me a whole lot with pcm.  I wasn't able to do it
last night, but I'll get a new kernel on the laptop tonight and try to
reproduce it with all-new bits.  I suspect, though, that I'll get what
that other guy got, a hang on the outw instruction.  (I suspect that the
zeroed-out *sc I saw was a remote-debugging glitch.)
