I remember no changes in mpd-5.6 that I would expect to cause this. Any 
way it should be trivial to check -- just build 5.5.

What do you have configured in mpd configuration and netgraph at all? 
AFAIR for plain PPPoE it is not very typical to use ng_queue at all as 
it doesn't requires stack unwrapping and at least few years ago stack 
size was sufficient to run all processing in one pass.
