Driver porting: The seq_file interface

is it normal to have more than one stop while reading a seq file ?

actually I have a list with 37 items but I get a "spontaneous" stop while processing element nine, and than a new start with the element ten (*pos=10).

after some hours (ok, two day :D) of debugging, it's all working now.. but it was really difficult for me to understand seq_file interface :D

thanks
