@rubo77, after identifying the problem to be likely with the Intel graphic driver, I've been testing Kernel 4.2.5-040205-generic #201510270124 SMP Tue Oct 27 01:25:49 UTC 2015 x86_64 for the past 6 hours, and it seems not to trigger any crash despite using 2D/3D graphic acceleration in Unity/Compiz and other applications.
