Commenting out the two calls to radeon_set_uvd_clocks() did not make any 
difference - still fails to initialize. BTW, this is also an EFI install. 
Sounds like for some people BIOS mode works based on the bug report.

Also confirming  that the suspend/resume issue persists with the 
SUMO_uvd.bin firmware loaded even if the UVD init fails. It is only by 
removing the firmware I can get the machine to suspend reliably.
