In this case I don't think that's the cause.  They do have the bad firmware
(which I'll update and test again as soon as Seagate provides a working fix),
but SMART reports no errors on any disk, and all self-tests past.  Linux has
been running on this machine for a while now under similar conditions with no
errors at all.  Also, there's a similar report with WD disks in ICH7.  (I've
opened kern/130726 for this.)
