[PlanetCCRMA] updates: new kernel for fc9/10

[Hector Centeno]

Thanks Fernando for the quick reply. Something I forgot to mention is
that I'm booting from an external USB drive that seems to be plugged
right into the USB with IRQ19, which is the one being reported in the
kernel failure warnings. Maybe If I install in the internal SATA drive
I won't get the locks.

Cheers,

Hector
