.config used to build the kernel

I have attempted to build a kernel with DRM and radeon firmware for a radeon 3850HD (rv670) card so as to set the graphics mode before the initrd loads.

I used a kernel.org 2.6.36-rc3 source with options based on the Debian Experimental 2.6.35. I have built kernel 2.6.36-rc3 successfully with DRM as loadable modules successfully, but with the kernel whose .config is attached, the kernel locks up at the message "loading RV670 Microcode" even though the microcode is apparently built into the kernel.

You are probably missing the rlc ucode which is available in the linux-firmware tree or here:

Comment 2 Arthur Marsh 2010-09-13 07:44:31 UTC 
After adding extra firmware to the build, the resultant kernel boots successfully.

Extract from kernel build log of kernel that boots successfully:
