This sounds similar to what I was experiencing on powerpcspe, and fixed
in head.  Can you try a 13.0-CURRENT snapshot from late November?  If
that works fine, then I think I know the change that fixes it, and I
can MFC it.  It probably should be MFC'd anyway, I just forgot to mark
it as such, so let it slip through the cracks.  The change in question
is r340653, so if you're able to apply just that change to 12.0 and
recompile your kernel (even cross-compile), and test it, that should
confirm my thought.
