dmesg with 3.14.3, mesa 469b42e

No... it happens at the first time I run es2gears. 
I tried with mesa revision 469b42e (where hawaii pci id were added) and your
patch, and I had the same visual results (ie a single frame from gear, and
apparent gpu reset) but this time there is a mention about gpu reset in dmesg
(I attached it).

If Hawaii acceleration has worked, I suspect the regression to be found in the
kernel module rather than in Mesa (or the issue was fixed and then broken
between november and now, but randomly picking commits around december didn't
bring me to a working state) and I don't think llvm to be the culprit here as
the isa is shared with bonnaire, which works. 

Unfortunatly I'm not very good at bisecting kernel regression, especially when
it can span several kernel release (from 3.12+ to 3.13). I can try but I don't
what kernel commit is a good candidate to start.
