I should have noted that I went to google before posting here, and the
problem is that there are a ton of hits, but no conclusive answers,
and even less information on how to decode the spew.  FWIW, the disk
in question for me is Hitachi.

As for why this appears in google on 2.6.18 and newer kernels, I
believe that's roughly when the libATA stuff was mainlined in the
kernel.
