As it turns out -- and I think I posted -- it is not lpd per se, but it's
invoking get_write_access -- in.telnetd does this too. The problem as someone
pointed out is that: (*p)->mm can sometimes be null... hence the null * deref.
to fix temporarily:
...linux/fs/namei.c: 130
if(!*p) -> if(!*p || !(*p)->mm)
