You don't have realtime permissions.  Are you sure you've got the
realtime LSM loaded?  How is it configured?

For this to work you either have linux-2.4 with the "capabilities"
patch installed, or are running linux-2.6 with an older version of
realtime-lsm with its `allcaps' option selected.  If the latter, try
setting any=1 or gid=<yourgroupnumber> instead.
