--- Comment #7 from Peter Asplund peterasplund@gentoo.se --- I don't know if I can bisect... I need some help in that case.
Gentoo has recently added a dependency on Systemd as a part of Gnome 3.8, and I think recovering from sleep/hibernate was working before that. But I'm not completely sure. Without systemd, sleep/hibernate doesn't work at all, so I'm unable to revert and test without it.
