Kernel Boot Problems

IRQ Probe failed for hdc & hdd
Boot freezes at:
IRQ probe failed for hdc & hdd hdc lost interrupt
This error occurs for some HD controllers under kernel 2.6.x.
A workaround is to pass the acpi=off
option to the kernel at boot time.
A different problem with similar effect has also been noticed. Apparently this is a problem with some hardware mixing with multiprocessor enabled kernels, and can be worked around by passing the nosmp
option to the kernel.

With the newer kernel, you normally get a initrd image file that you should also configure in your grub config or lilo.conf. You get that file because most of the stuff is compiled as module and that's why you need the initrd file, it will load the required modules.
Here's a small example of how your grub config should look like:
