What motherboard do you have? Apparently the newer kernels are not happy
with your combination of motherboard and hard disk. I don't really know
enough to fix this. You could try to boot with/without acpi (acpi=on in
the redhat kernel, acpi=off in the Planet CCRMA kernel, add this in the
kernel boot line in /etc/grub/grub.conf), just in case routing of
interrupts is the problem (does not seem so). 

Have you tried the latest Planet CCRMA kernel? I have not released it
officially because of lack of time but it is working fine. To get to it
put another line in /etc/apt/sources.list, same as the planetcore, but
replace planetcore with planetedge. "apt-get update" and then "apt-get
install planetccrma-core". It's 2.4.25...
