I am having similar problems to Antonio with the miner. My environment is following:
-Ubuntu 14.04
-Biostar HB61 + 5 x 7950
- AMD drivers 14.6 beta
- AMD APP SDK installed version 2.9
- miner compiled with make -j=5
once I start mining in simple wallet using start_mining 5 I am getting following:

any thoughts?
If necessary I can also downgrade to Ubuntu 13.10 with AMD 13.12 drivers. (althought it would take me several hours)
