Problems adding modules/etc to Corepure64

I'm not sure this is the right place for this question - happy to see the topic put in the right place

As a step toward patching the 3.8.13 kernel and building some modules, I'm trying to build a plain-jane corepure64 bzImage. I'm following the wiki and every forum post I can find (both here and off-site). On an HP 6910c laptop, everything works - both stock and custom.

On an Acer c720, stock works and custom fails. I can get to a terminal with base norestore on the custom bzImage. Once I load modules, though, the custom version incurs random crashes, complaints from udev and the pci hardware, etc. My PCI/graphics hardware just doesn't work with my custom bzImage. It doesn't matter whether I use the repository modules or my own. I'm really stumped. I can't figure out what is different between stock and my own. I'm thinking it has to be a module problem, right?

My build scripts are attached:
- build-stock.sh: compiles new bzImage + modules from source
- dupe-gz.sh: creates custom.gz by replacing the modules in stock corepure64.gz.

Then I put these two in my boot directory for GRUB, etc.

I've tried the build both distributed (distcc/ccache w/ identical kernel and gcc/extensions on each system) and locally (no distcc, cleared ccache), rebuilt a few times. No luck.

I'll collect a dmesg and add that. Primarily errors/segfaults after installing the graphics modules. Changing the order of module loading helps reduce the number of errors, but only intermittently.

Advice/suggestions?

Juanito:
Are you using compiletc from the x86_64 repo or toolchain64 from the x86 repo?

It's probably worth trying with both.

dentonlt:
Good call. I'll try toolchain64.

Clarification: do I need to roll my own module extensions, avoid the repo versions? I was assuming not, since I'm basically rebuilding stock.

EDIT: tried using my own module extensions, doesn't help. [sigh].

dentonlt:
dmesg output from custom + custom module extensions. All this built/ran from the x86_64 repo. gpf during modprobe.

curaga:
There are a few issues with recent gcc and that kernel version. The older gcc in toolchain64 was used to build it and worked fine.
