[Pw_forum] why phonon calc stops at the first mode

Dear All,

I am doing the scf and phonon (at G) calculation on a 2x2x2 fcc Ni supercell (a 
serial calc using parallel code on single node). The scf finished properly, but 
the phonon calc stops at the first mode without any error/reason. Message 
gives "running the phonon calculation at Gamma... done". If interested, pls 
check my input and .out info as attached below. 

Could you give me some hints on possible causes of such problem and how to fix 
it? Thanks very much in advance for your kind help...

Best regards,
Yong
