Ok, my laptop is back to the business, I finished the bisection and I
have a completely different result from the first time:
commit 719429a54d9c: "drm/i915: write backlight harder"
I reverted it on top of 3.8.1, as expected that fixed the issue.
By the way it is reverted in the last drm pull request sent by Dave
Airlie.
I guess it'll be spread in stable‽
