Drm-intel:
The bisected to commit: f8fcadba218fe6d23b2e353fea1cf0a4be4c9454
Reproduction steps:
On BDW/HSW brixbox X crashes right after boot or when running multiple
benchmarks (unigine -> glbenchmark -> gfxbench)
Is bit hard to reproduce. At least with HSW laptop it seems not to be
reproducible.
1. Reboot machine with that build
2. If X does not crash try running multiple benchmark test. Try running in this
order unigine -> glbenchmark -> gfxbench
