I just managed to get the 4.4.0-24-generic kernel to a proper suspend and resume for several times. As mentioned in the several bugs reported here, it seems to affect users with Intel/ATI hybrid graphics.
I disabled the ATI part by editing /etc/default/grub line to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0" and a "sudo update-grub". After this my laptop (Samsung Ativ Book 730U3E) suspends with the official Kernel.
