[LITMUS^RT] Bad address

[Aaron Block]

I just upgraded to the newest litmus and liblitmus and wanted to make sure everything was working properly. 
setsched and showsched both work; however, I'm having a problem creating real time tasks.  Specifically I keep on getting "bad address" errors regardless which scheduling algorithm I use. I'm using 2-processor Xeon MacPro with 6 cores on each processor. 


Any suggestions for how to fix this?

Here are the error messages...


rtspin 10 100 10 gives me the message
	could not setup rt task params: Bad address

runtests gives me the output
