So I've spent the past weekend trying to get this IBM Xeon server up and running. I also took this opportunity to try and get a bootable GPT/Grub2/BIOS setup going.
I am able to get the kernel booted, but I immediately get kernel panics. The kernel on the Gentoo LiveCD works fine. I've tried Gentoo and Vanilla sources and constantly see stack traces like the following. I've done a lot of searching and haven't been able to find anything useful.
I've tried disabling CPU Frequency scaling (based on some mailing lists that had a similar stack trace), but it gave me the same stack track on boot.
