[Pw_forum] problem in hybrid pseudopotential calculations

[Muhammad Adnan Saqlain]

Dear users
I have been to vc-relax my system with hybrid pseudopotentials. However, I
always end up with this error message.


 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine electrons (1):
     dexx is negative!  Check that exxdiv_treatment is appropriate for the
system.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


Although, in previous emails, I was suggested to turn off
x_gamma_interpolation. However, this is not solving my problem. The first
BFGS cycle runs smooth. However, in the second cycle I get this error
message. The pw.input and pw.out file attached.
I shall be grateful if anyone can help me to solve this issue.
