I have a Lenovo z50-70 with a core i7, GForce 840m and recently install the Kernel 4.6 and the problem is solved. I copy the commands: cd /tmp wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/linux-headers-4.6.0-040600_4.6.0-040600.201605151930_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/linux-headers-4.6.0-040600-generic_4.6.0-040600.201605151930_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/linux-image-4.6.0-040600-generic_4.6.0-040600.201605151930_amd64.deb

Suspend/resume worked flawlessly with linux image 4.4.0-15, and after standard upgrade yesterday (5/04/2016) which installed image 4.4.0-16, the system freezes when attempting a suspend. I get no response from the system (nor keyboard, nor screen, nor touchpad), but it gets very hot, so that it must be running something. Booting with 4.4.0-15 makes the suspend to work perfectly.
