   Page Fault Trap in _bcopy in _comstart in _slstart in _comintr

   _bcopy(f867b240, f7bffc0c, 10, f866af02, f867b240)

   _comstart(f867b200)

Please send the *exact* text from the kernel.  What you included
(above) is actually *very* confusing.

   What I don't understand is why q_to_b has a while loop.

It's a while loop because the first round doesn't necessarily copy all
the bytes that were requested.
