OK, thanks. Some very minor progress:


   ipcs: headers                        ... OK
   ipcs: limits overflow                ... SKIPPED (no root permissions)
   ipcs: basic limits                   ... OK
   ipcs: mk-rm-msg                      ... FAILED (ipcs/mk-rm-msg)
   ipcs: mk-rm-sem                      ... FAILED (ipcs/mk-rm-sem)
   ipcs: mk-rm-shm                      ... FAILED (ipcs/mk-rm-shm)

   3 tests of 6 FAILED

But I did find

I just don't know what argument it was trying to pass.
