It shouldn't be hard to see in *Messages*. For example, if you do

emacs -Q
M-x load-library vhdl-mode <RET>

you'll see this in *Messages*

  Loading vhdl-mode...done
  Package assoc is obsolete!

Or, as a last resort, you can temporarily rename
lisp/obsolete/assoc.elc? and see which package from your .emacs fails
to load :-)
