So, I tried http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.4/ and switching to external display and back multiple times, including suspend/resume cycle works flawlessly. Unfortunatly, I am unable to remount my XFS root writable (had to change initrd option) and compile the ZFS DKMS files. So, for now this is also not a real solution...
