# Are you using an InitialRamdisk (initrd?) If so, do you have CONFIG_BLK_DEV_RAM and CONFIG_BLK_DEV_INITRD enabled in your kernel?
# The kernel was compiled for a different architecture - for example, it has optimisations for [AMD] chips that don't work on an [Intel] chip, or vice-versa. If you changed the architecture of the kernel config (well, for kernel v 2.4 at least), you *need* to do a make clean afterwards, otherwise some object files that should be re-compiled aren't.

My machine (kernel 2.4.21) hung after printing this. (Athlon 2000 XP on an AD77 motherboard (KT400)). It is caused by [APIC] support in the kernel. Booting with the "noapic" kernel flag didn't fix it (although it made the machine go into an infinite loop printing an error about apic on cpu 0). Recompiling the kernel without APIC support resolved this.
