Updated the printf in psycho_set_intr() a bit, and I can't see why
the last one would fail, and the earlier ones work. Just in case this
info helps anyone else, though it looks pretty normal and non-
so what this instruction is doing is setting the "valid" bit in
the interrupt mapping register.
i'm guessing that some extant interrupt is then delivered and the
system isn't prepared and we go boom (aka hang.)
