[petsc-users] KrylovSchur solver diverges when setting EPS_GHEP

I mean the solver does not converge. 
Whereas if I do not specify that the matrices are symmetric and 
generalised non-symmetric eigenvalue problem is considered, everything is all right. 
However, i am sure the matrices are symmetric. 
I double check it with MatIsSymmetric.
