Using mesa 0967c362bf378b7415c30ca6d9523d3b2a3a7f5d (and for a long time),
piglit tests fail and hangs the system (ssh session won't respond). Using an HD
6950 (Cayman).

Running "python2 piglit-run.py --no-concurrency tests/r600.tests
results/r600.results/", it fails everytime. According to the "main" file, the
last log info is:
