Nbd-2.4.15 isn't on the ftp site. It's available only by http, file by
file! (I know it isn't available, because it's the one I am working on
and I haven't released it yet). Do you mean nbd-2.4.14 ?

The client and server don't matter, it's the MODULE (nbd.o) that must
be compiled with __SMP__ defined (and -O2, of course).

That's a module problem. Convince me that you compiled the module with
__SMP__. Show me the kernel log (dmesg).

module behaves badly. Show kernel messages (and convince me that you
compiled the module with __SMP__ !). Show me output from /proc/nbdinfo
too. If it isn't there, end of story (failed module install, hence
failed module compile).
