"Aruba" is the default firmware and probably that's not what you want. 
You need to find your own chipset and build correct flavor(s) for you.

Do "grep 'could not load firmware image' /var/log/messages".  For 
example, you will see something like this:

May  2 21:48:35 xxxxxx kernel: drmn0: could not load firmware image 
'radeon/TAHITI_uvd.bin'
May  2 21:48:35 xxxxxx kernel: drmn0: could not load firmware image 
'radeon/TAHITI_vce.bin'

This means you need need "tahiti" firmware and you will have to build 
and install it.  Note you may need multiple flavors.  For example, I had 
to build two flavors for the above GPU, i.e., aruba and tahiti.

May  3 08:46:38 xxxxxx kernel: drmn0: successfully loaded firmware image 
'radeon/ARUBA_pfp.bin'
May  3 08:46:38 xxxxxx kernel: drmn0: successfully loaded firmware image 
'radeon/ARUBA_me.bin'
May  3 08:46:38 xxxxxx kernel: drmn0: successfully loaded firmware image 
'radeon/ARUBA_rlc.bin'
May  3 08:46:38 xxxxxx kernel: drmn0: successfully loaded firmware image 
'radeon/TAHITI_uvd.bin'
May  3 08:46:38 xxxxxx kernel: drmn0: successfully loaded firmware image 
'radeon/TAHITI_vce.bin'
