For me, hibernating works almost perfectly (see audio problems on resuming, Bug #80893), but the computer halts after hibernating.
I just tried suspending right now, while I was editing this comment, and the computer also halted after the suspending. By the way, suspending doesn't suffer the Bug #80893 -- Kernel 2.6.20 reboots instead of shutting down https://launchpad.net/bugs/71040 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
