Description

I updated to the kernel 3.14 provided by Archlinux (https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/linux&id=b29f29eb9641d5abcdcd3a5a70c73999c0cf1557) and I'm not able to boot without passing radeon.modeset=0 to the kernel command line.

The kernel 3.13 from package 3.13.8-1-ARCH is working properly.
