glxinfo while running the different kernels, plus lspci

I can't get 3D acceleration with the following kernels:
- kernel-default-3.16.7-45.1
- kernel-desktop-3.16.7-45.1

The old kernel-default-3.16.7-42.1 was working fine and I can successfully workaround the bug by booting kernel-default-3.16.7-42.1 agai (sadly that's no good choice because of the critical security fixes in 3.16.7-42.1).

Interestingly kernel-vanilla-3.16.7-45.1 is working too.


So it appears, that some openSUSE patches in 3.16.7-45.1 break 3D acceleration.

My PC is having an onboard "Radeon HD 4200" card, but I'm using an dedicated "Radeon HD 6450".

Sadly I couldn't diff-out the critical part in the changes between 3.16.7-42.1 and 3.16.7-45.1. But maybe someone else has a clue!?

I attached lspci output.

And I also attached glxinfo output while running the different kernels. In that files you can clearly see an "libGL error" and kernel-default-3.16.7-45.1 only offering "Gallium 0.4 on llvmpipe" (which means software-rendering - as far as I know) instead of "Gallium 0.4 on AMD CAICOS".
