 Ah.
 
 That is odd - given that the only way you should be getting SIGSYS is
 if the nfssvc() syscall doesn't get installed, and that happens as
 basically the first step in the module initialization. (Which is
 supposed to be called whether or not the code is compiled in or loaded
 on the fly.)
 
 And if there's something it depends on that's missing, in the builtin
 case that ought to just result in link failure.
 
 Are you sure it loads/attaches successfully? If it starts to load and
 then unloads itself for some kind of error, it will uninstall the
 syscall and then nfsd won't go.
 
 My inclination would be to add some printfs in that initialization
 code to see where it does and doesn't get.

 Maybe someone broke module initialization.
