I was getting something similar and it turned out to be because a *different* 
span was configured in chan_dahdi.conf, but not connected to anything.

Make sure, if you're only using 3 of the 4 spans, that all lines relating to 
the unused one are commented out in /etc/asterisk/chan_dahdi.conf  (and maybe 
in /etc/dahdi/system.conf as well).

I'm guessing this is due to a change in default behaviour between libpri or 
DAHDI versions  (since an older install worked just fine with "broken" 
configs).
