Thx for the new Kernel AceLan!

I tested the x86_64 version on two different Boards. It got a little better I think - bug happens not that frequently imho.
But still, if I e.g. press alt-f2 in Unity and start typing I still get lags and dmesg shows:

[ 85.166147] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 39358, at 39358], missed IRQ?

It's better reproducible if you play some opengl game. e.g. neverball.
