as far i know the only bootloader thats efi compatible that runs on phenom is chameleon. Im guessing pc efi v9 is what the dvd boots off as its the default one that installs so im guessing thats why the kernel panic. I know my distro boots on phenom it was built just for that reason. This is by no means an advert for mine as i believe ipc is better but im guessing it has issues on phenom. With my distro you would have to add your chipset kext unless you installed via usb which you would have to do for dvd and ide/sata. The bootloader compatibilty info may be incorrect. But at the time i built mine chameleon was the only one that would allow efi (on phenom) so to me this makes sense
