Please disredgard this query... a little more persistence in googling
and I hit a post from 2009 that explained it.

It was a kernel config shortcoming on my part: CONFIG_LBDAF was left
unset.

I think I may have even run across something about that when perusing
the handbook install section but when I got there during
`make menuconfig'  All I can say is the way that section reads about

   --*-- enable block layer --*--
      [*] Support for Large (2tb+) block devices and files

kind of makes you think its something you don't need. But then
thinking again... with todays massive drives......
