[Buildroot] buildroot-2012.08: Handling drm module

Hello,
Build is OK.
The resulting image boots OK.
But the screen flickers with this image.
The image was not built with buildroot.
I built vanilla 3.4.7 downloaded from kernel.org
With knoppix 7.0.4, when I boot with: "knoppix 2" there is no flickering.
When I boot with "knoppix 2 nodrm" the screen flickers.
Is "nodrm" a boot parameter (like vga=normal) ?
Thanks,
Zvika

Can you explain what your problem is? Is it that the build fails, or that
the
resulting image doesn't boot, or that the screen still flickers with the
buildroot image?
In any case, it is probably a kernel problem. If you use exactly the same
kernel
version and kernel configuration as in knoppix, you should get the same
behaviour.
(You can usually get the configuration of a running kernel from
/proc/config.gz).
Note that knoppix may have additional kernel patches as well.

Arnout
