Yes I have it. But I get the same crash on various 4.4.X and also with
4.5.3.

Also I compiled 4.2.28 / 4.1.X and it works fine with this processor,
using i915.preliminary_hw_support, but we are experiencing problems with
suspend/wakeup (but that's another story)

Also there are more reports about the same crash with this kernel
compiled by someone else:
