[Pw_forum] Fwd: problem when calculating the electron-phonon coefficients

Dear pw users,

I'm performing some calculation of electron-phonon coefficients on Bi-V
(bcc) . The first two steps converged well. While doing the third step, I
got the message like ' *kpoint  10 ibnd  17 solve_linter: root not
converged  0.258E+00*' as seen in the following output file.
Input file and specific output file are in the attachment.

Thanks for your advice.
