Yes, I uinderstand why I have the rt kernel installed, what I don't understand 
is why whenever I install the Planet CCRMA rt kernel it becomes the default 
selection in the bootloader upon installation. Traditionally on Fedora (perhaps 
ol' RHL, too, it's been a while) when a new kernel is installed it goes to the 
top of the list, but the previous default remains the same for the user to 
update, in case there are any incompatibilities with the old kernel. That was 
the "protocol" of which I spoke.

I am sending the links for both of the rt kernel errors to the email address you

I don't quite follow. What do you mean by "out of protocol"? If you have the 
Planet CCRMA rt kernel, it is because you either installed it manually with yum 
(after adding the Planet CCRMA repositories), or installed the planetccrma-core 
package that brings it in. If you do that of course it becomes the default! (but 
you can still can boot the original Fedora kernel if you so desire). One of the 
goals of Planet CCRMA is to add the rt kernel and associated utilities for best 
rt performance.

Thanks. I see that this was automatically gathered by abrt... It would also be 
best to  cc' the linux-rt-users at vger.kernel.org mailing list on rt bug reports, 
those are the gurus that can solve rt related problems :-)
