[Pw_forum] cannot bracket Ef

[Marcello Rosini]

Dear all
I got this error from a relax calculation

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
      from efermig : error #         1
      internal error, cannot braket Ef
  %%%%%%%%%%%%%%%%%%%%%%%%%%%

I am using a smearing, thus I do not have the problem of unsufficient 
number of bands.
The program makes a number of relaxations cycles and then stops.
I did not find anything useful from the older post in the forum.

Here find the input and the output

Any suggestion?
thanks
Marcello
