[PlanetCCRMA] updates: new kernel for fc9/10

[Tracey Hytry]

Thanks Hector for posting this.
I was just getting ready to leave Fernando a message about the same thing on the 32 bit system I have.

It looks like the kernel is using the old style ata drivers, where I think that Fedora has been using the new disk drivers for quite a while.  This I'm not sure of until I get a chance to compare the kernel config files, but I suspect this is what's part of the problem.  Of course, if it is, will the newer disk drivers work whit the rt patch set?

Here's part of dmesg for the 32bit machine:

Oh, and BTW, the new kernel gives no errors and works fine on the 64 bit machine.
Later I may get a chance to give it a full audio/midi- test/workout.
