Was about to test 3.10-rc5 but kernel freezes during boot.

With freeze, I mean I've to hit reset button to recover, system is
basically dead, last line on the screen is:

--
fb: conflicting fb hw usage radeondrmfb vs EFI VGA - removing generic driver
--

With a *working* boot on plain 3.9.0 I get this:

drm/radeon: UVD bringup v8

Just everything needed to decode videos using UVD.

v6: just all the bugfixes and support for R7xx-SI merged in one patch
v7: UVD_CGC_GATE is a write only register, lockup detection fix
v8: split out VRAM fallback changes, remove support for RV770,
add support for HEMLOCK, add buffer sizes checks

I have these firmware files:

and they are builtin into the kernel:
