--- Comment #23 from Alex GERARD <alx.gerard at online.fr> ---
I have the same problem using:
Software :
- Linux 4.2.0 (From updated Debian stretch/testing) with
i915.preliminary_support=1
- xf86-video-intel: 2.99.917 OR Git from 2015.10.19 from debian experimental)
- Dell U3415W (again !) via DP 1.2 (no MST *usage*)

Hardware :
- Asrock H170 Pro4
- Intel *Skylake* i7 6700

The whole system freezes after giving the exact same error as reported here.

I have tried Linux 4.3rc7 too without success (I did not managed to catch the
entire kernel output debug via NetConsole this time before freezing).

Hope it will help.
