The most recent build of linux-am33x built properly. http://archlinuxarm.org/builder/in-log/linux-am33x-3.8.13-4-armv7.log.html.gz
Are you building the kernel from our github with makepkg?

Yes, I used the PKGBUILD from core/linux-am33x/...

Your log shows that it was compiled, without errors. No idea what went wrong on my setup, I will try again...
