Soon after upgraded from Debian 7.7 to 7.8 suspend to ram (and hibernate, s2ram, s2disk) didn't work. I installed linux-image-3.2.0-4-amd64_3.2.65-1+deb7u1~test_amd64.deb and now suspend works but not hibernate (sistem immediately reboots). My machine has a Intel core i5-2500, 4 GiB RAM, 1TB HD. If do you need more details please let me know.
Kind Regards Giuseppe
