Hello,
I tried to build a 2.6.33 kernel but on boot it dies on modprobe
(kernel-Oops). This might be the result of faulty config, but I'm
totaly clueless what's the fault.
The kernel starts up fine and mounts the root-filesystem, but then
dies on the first modprobe executed. I can boot it with init=/bin/bash
and get a working bash (until I do modprobe on any module).
System is a Gigabyte M55S-S3 rev 2.0 (nForce 550) with an AMD Athlon64
X2 5000+ and amd64-kernel architecture. kernel-sources are from
kernel.org.

I have attached the config and the complete kernel-log of an
boot-attempt.

You snipped too much. The full backtrace is useful:

It seems something is wrong with forcedeth code or PCI code.
Adding some Cc's.
