--- Comment #24 from Sunil Kamath <sunil.kamath at intel.com> ---
Summarizing various experiments:
- Animesh/Tvrtko tried various experiments to route cause the problem.
- As discussed/mentioned before major issue seems like:
1. Handling power infrastructure for headless system.
2. How to make headless system really headless in real way.

For 2nd test, below option was tried:
i915.disable_display=1 and with this issue goes away.

In addition to the above various experiments were done.
Imre to confirm back if already done experiments are sufficient to get answer
to both 1 and 2.
