I Konrad, first, thanks for your input and your time, it is much appreciated.
I understand that those changes are torward the linux kernel, which is used by xen compilation. I applied the changes and i'm rebuilding Qubes with xen 4.6.1 based on a kernel-4.1.24. Will test the build in the next days and post back the results. output of sudo lspci -v from dom0: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
