I'm not the driver author, but taking a quick look at the source code
this seems to be working as intended. Is just debugging information and
you don't need to worry about it unless you're actually debugging how the
driver works. If I were you I would just disable ATH_DEBUG.

If you're interested about the specifics, adrian@ might be a good person
to contact as he's the author of that code.
