As it turns out, it looks like treating my IBM branded drive as a
Toshiba does fix the problem. I have no idea why it would have started
appearing after changing to CAM.
I've attached the trivial patch I've used, but I don't know whether
it's appropriate for widespread use. I understand that my drive is
really an XM-4101, but I don't know whether it's generally true that
IBM drives are really Toshibae.
