from the help file:
Unsuccessful results from the underlying LAPACK code will result
in an error giving a positive error code: these can only be
interpreted by detailed study of the FORTRAN code.
from the manpages:
INFO (output) INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.

I don't know what DBDSDC is, but it appears that there may be some convergence issue for you. Unless someone else has better ideas, look up www.netlib.org/lapack and the routines in there to investigate further.
