tested r.basin here on my side:

r.basin --verbose map=dem_linked at PERMANENT prefix=a
coordinates=-51121.42352,193901.704819 dir=C:\tmp\rstreamtest
threshold=12000
[...]
(Sun Nov 16 13:12:48 2014) Befehl ausgeführt (40 Min 25 Sek)   

r.basin finishes here.

please try to reset and align your region to the DEM before a r.basin-run.
