Custom built Live CD using Gentoo not booting properly on all machines.
 

I've been working on creating a Live CD with the tools I want, just for my use with system recovery and repair. For the most part, things have gone very well. The Live CD actually works fine, somewhat. I have run in to a problem where it doesn't actually boot on a lot of hardware.

What happens is during boot, while the modules are loading, the boot process hangs and the disc drive spins down. While I thought it might be a kernel problem, I'm using the .config from the latest gentoo Live CD, which boots fine on the same hardware. I am out of ideas. If anyone has any clue, then please help.

You can try various safe setting for boot parameters. Usually, custom live-CDs are made for particular hardware systems, but you just wanted custom software included.

boot parameters

I haven't found anything that has affected the boot. Unfortunately the debug messages tell me nothing as it gets past the initial kernel boot and then stops while loading modules.

I could upload a copy of the Live CD if you'd like to take a look at it. It's only 200MB.
