problem with Wannier block in MD

[tfran... at gmail.com]

Dear all,
I am newbie in CP2K code. I am running a MD, and after a 3 ps of 
equilibration, I added the Wannier block in order to compute the Wannier 
functions associated with the atomic positions for post processing the 
corresponding wannier.xyz output with TRAVIS. I added the Wannier block and 
at the same time I changed the parameter of the thermostat in order to 
start the full production. The point is the the time per cycle increase 
abruptly and honestly I don't know if there are some parameters to tune 
properly. In the output, also, the CRAZY method does not CONVERGE, and CP2K 
automatically switches to JACOBI. 

Can someone kindly help me fixing this problem?

Here I provide the input file, the part of the energy file in which the 
time per cycle increased a lot and the line of the output file.
