kernel-rt-2.6.22.6-1.rt9.5.fc7.ccrma is the previous one, you could try to 
install that one and see if it works[*]. What were you running before?

[*] as it is an "old" kernel you will need to:
   yum install yum-allowdowngrades
and then:
   yum install --allow-downgrade kernel-rt-2.6.22.6-1.rt9.5.fc7.ccrma
I think that should do it...
