Hi. Any update on this?
I've pushed the workaround upstream. So you should at least have a booting system. Just don't try to use any accelerated video decoding since that would crash the box again.
My best guess is that the information in the BIOS about the reference frequency is wrong, but without having the hardware here I can't do much else to get UVD working properly.

I just noticed I'm getting the following errors during the sleep and wake up cycle:
[drm:rv730_stop_dpm] *ERROR* Could not force DPM to low [drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed
Kernel is 3.14.2-1-git-dirty with above patch
Sounds like an unrelated DPM problem to me, but who knows.
