Well, yea, that part I thought might be different too, but I did
hear someone saying they had seen the bug on a SS10, so it might
be more general than just ESP100.  Just out of curiosity, what are
the effects of the bug?  Hang at boot? Panic at boot? Panic on
heavy usage of a tagged disk? Random lossage and data corruption?
