Dear pwscf users,
    Recently, I encounter a problem about neb, I intend to calculate the neb about adsorption, unfortunately, power cut, so I want to restart the calculation following interrupted task by using 'restart', but when I restart the calculation, error information is displayed. 
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from cdiaghg : error #       238
     info =/= 0
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     stopping ...
p0_3953:  p4_error: : 0
Input and output is displayed as follows, I hope I could obtain your help, I will be grateful. 
Best regards
