--- Comment #4 from Jerome <an.inbox at free.fr> ---
In reply to comment #3, check bug #89915 comment #7 indicating a fix in 4.0.7
and pointing to a patch.

In my case, just like the initial reporter I'm running Debian Jessie (stable)
with a backported Intel driver 2.99.917. Same hang issue with the stock kernel,
but installing kernel 4.0.8 from Debian unstable fixed the issue.

Before updating the kernel I also tried the "i915.enable_execlists=0"
work-around and it worked ok: either no hang, or a hang but quickly and
automatically recovered.
