First, thanks to Pat and his team for their hard work.
Next, I have an Ati Radeon Xpress 200M on my laptop, and since Ati droped support for it, I depend on the radeon module from the kernel. Since todays upgrade, I am unable to start X (there are errors with "modprobe radeon"). Has anyone else experienced this problems?

This is the error I get:

It would be useful to know which distro you are using, or if it is a custom distro like (LFS), and did you compile the kernel or just download it from your distro repos?

I said -current, so it is Slackware 13 Current, since we are in the Slackware forums. Plus in my signature, is posted the distribution I use.

I have the same issue with intel driver. Perhaps someone knows the solution?

When you upgraded the modules, you also upgraded the kernel, right?

yes.

Strange... I only saw this happens when loading a module compiled against another kernel version. Look if you are booting from 2.6.33 (uname -r). Check if, for some distraction, you installed the modules for the right architecture (32 or 64bit).

Well I can assure you that the radeon driver loads and works fine in 2.6.33 as I'm using that currently on two workstations. Are you using a kernel you built yourself or a packaged one (I'm not sure what -current currently uses as I'm still on 13.0)? Does anything else show up in 'dmesg'?

Check that you have the same version kernel and modules packages. It can happen sometimes.

I upgraded full, even reinstalled all the kernel packages.

Today's upgrade totally trashed the radeon/drm/ttm etc... kernel modules.
Using the -smp kernel image + modules from -current gives the following errors (other modules loads fine, except radeon and its dependencies)

The installed and relevant packages versions are:

kernel-headers-2.6.33_smp-x86-1
kernel-huge-smp-2.6.33_smp-i686-1
kernel-modules-smp-2.6.33_smp-i686-1
kernel-source-2.6.33_smp-noarch-1
module-init-tools-3.11.1-i486-1

I was having similar issues with the nvidia driver. Take a look at your kernel .config file and see if you have this:
If not, then go ahead and make those changes and rebuild your kernel. That's what I had to do in order for the NVIDIA drivers to work.

Hope this helps!

rm -rf /lib/modules/2.6.33
upgradepkg --install-new --reinstall /{path to your local slackware mirror}/slackware64/a/kernel-modules-2.6.33*.t?z should do the trick.

Well, I can say just +1. My workstation (dell optiplex 760) has intel video using intel 915 video module and it fails with the same "Invalid module format" warnings. There are warnings about failures for other modules, but I'm not sure about them - one was for button.ko. Later I can provide more information.

how about lilo?
