I have a couple of systems here that are refusing to boot after the installation of CentOS 4.3 when done through Kickstart. They boot fine when installed from CD. The boot hangs after grub loads the kernel and initrd. The cursor is still flashing. The strange thing is that the same drive containing the OS installation boots fine when moved to a slightly older system (older system uses Nacona CPU. New system uses Irwindale CPU. Both use the same motherboard). Any idea how to troubleshoot it at this point? I've tried disabling USB, APIC, etc. without much luck. Thanks for any help.
