[2.6.30-rc3][Regression] Compilation failure

[Rogério Brito]

Hi, people.

I'm trying to compile a new kernel for a x86_64 computer using Debian's
sid userland and I'm getting the following error:

In fact, I have not been able to compile a 2.6.30-rc* kernel yet, due to
errors like these. The full .config that I'm using is available at
<http://rb.doesntexist.org/linux/>.

Any help with this regression is more than welcome.


Thanks, Rogério Brito.

Still got the very same error after applying the patch.

Reading it, I saw that it regarded the modesetting being enabled. I
don't have it selected on my system. Is there anything else that I could
try?


Thanks, Rogério Brito.

Even though I have no modesetting compiled in the kernel, I *did* have
the options VIDEO_OUTPUT_CONTROL, BACKLIGHT_CLASS_DEVICE, INPUT,
ACPI_VIDEO enabled, but two of them (BACKLIGHT_CLASS_DEVICE and
ACPI_VIDEO) selected as modules.

Selecting them as "y" fixed the compilation problem.

I guess that you just wanted to know this.
