dc0: failed to force tx and rx to idle state

I was getting this message on my FBSD 5.0-RELEASE box
when transferring large amounts of files (like a cd's
worth of mp3's - it's an mp3 server).  So I decided to
update the 5-CURRENT to help out with testing before
the 5.1 release and to see if the message goes away.  

It's still there

I assume, from the little bit of research I've done on
this, that it's harmless, but annoying.  Is this
something that you're wanting to fix before 5.1R?  If
so, I won't mind helping locate it.

uname and dmesg output is below (I also get this
message about 4-5 times while just booting the
machine).
