The drive is actually offering IU and QAS. That's fun; I've never seen a u160 drive that could do those before. Although the aic7xxx driver is apparently coded to allow this, it looks like the code paths have never been exercised. So, although I think this patch will fix up the first error, there's probably a long line behind it ...
