[PlanetCCRMA] Re: JACK isn't getting realtime

I also cannot get realtime going with JACK on FC3.   I'm using the rdt 
kernel with jackd, but I get an error message (jack_create_thread: error 
-1 switching current thread to rt for inheritance: Unknown error 
4294967295), and no apps can connect to JACK.

"/etc/rc.d/init.d/rtload status" gives:
Realtime kernel module is loaded, current parameters are:
   any=1; gid=-1; mlock=1

My only conclusion is that there might be a hardware/driver conflict (?).
