From an ARS Technica story:
Linux 3.15, expected to be released in mid-2014, "will feature a large number of ACPI and power management updates" and allow Linux-based computers to suspend and resume faster, Phoronix reported today.
'Visible to users with the Linux 3.15 kernel should be reduced time for system suspend and resuming, thanks to the enabling of more asynchronous threads,' the article said, pointing to a list of changes posted by Rafael Wysocki, an Intel employee who maintains the Linux kernel's core power management code. Basic support for Nvidia's Maxwell architecture is also in the works for Linux 3.15.

I just want a kernel that'll resume at all after a suspend. Ever since a warranty-replaced mobo a couple years back every distro/kernel version I've tried never comes back unless I hard shut-off and remove the battery. Even the one (ubuntu 10.04) that worked before the repair. It was enough to drive me back to windows 7.

Hibernation is what I end up using most. Suspend on Linux has always been terrible, and it's hilarious that in 2014 it still is unstable on so many boxes. Thankfully, I usually just leave my towers running, but the netbook sometimes gets hibernated.

Suspend on my Dell E6400 laptop works perfectly. I just close the screen, and open it later and it comes right back after a short pause. It's great. It's a lot better than Windows in fact; I have an E6420 (later generation of same basic laptop) for work loaded with Win7, and this thing takes forever to un-suspend, with lots of screen flickering to boot.

If you want the best of both worlds -- suspend for, say, a couple hours, then go into hibernate (so your battery isn't drained from being suspended for a couple days), take a look at this ask-ubuntu question, and the accepted answer:t omatically-from-suspend-into-hibernate [askubuntu.com]
http://askubuntu.com/questions/12383/how-to-go-au
This works by setting an rtc timer event to kick off a couple hours after suspend, to wake up and then go into hibernation.
Note, that it is highly recommended that you initially set the timeout to something low (such as a few minutes), and try it out with several different system loads, to make sure that hibernate works correctly after suspend. Otherwise, your laptop may come out of suspend, fail to hibernate, and then be left in a powered on state when it is in your laptop bag.

my Dell
Oddly enough, when rudolph mentioned "warranty-replaced mobo", that brand was the first thing that came to my mind.
I remember a former Dell employee posting at the other site about that company's actions during the days of counterfeit lytics. [googleusercontent.com] (orig) [atariage.com]
He said that when MoBos were returned, they would give those a quick visual inspection and if nothing odd was spotted, they were instructed to ship those out as replacement boards to others who had problems.

Yeah, nevermind the speed, just make it work reliably in the first place!
I'll add my little anecdote to the pile. I use Trisquel GNU/Linux. Originally suspend/hibernate wouldn't work. Everything seemed peachy until I tried to resume/thaw. Then I fucked around with quirk parameters and LO AND BEHOLD both started working! However, all things come to an end, a newer version wouldn't no longer work despite my best efforts.
This clusterfuck is very much related to the horrible driver/firmware situation with the vanilla kernel chock full of binary blobs. Linus, it's time to clean the house.

Trisquel
For those who haven't memorized the names of every distro in existence, that is the one that the Free Software Foundation advocates.
The Trisquel developers make no concessions to brands/chipsets which have only proprietary device drivers available; if your driver is not Free Software (source code available), they won't include your stuff in their build.
If you go to BuyMore and want to determine how openness-friendly[1] a system is, run Trisquel from your plastic disc / thumbdrive and if everything Just Works(tm), you know that every manufacturer whose stuff was integrated is a supporter of software freedom.
[1] Another way to say that is "obsolescence-resistant".

This has to be specific to your hardware.
We have two laptops running Kubuntu 12.04, and they suspend and resume reliably each and every time. This has been the case for years, and worked on 10.04 as well.
Nothing special to configure suspend. I hit the power button and the laptop sleeps. I open the lid and it wakes up. Sometimes I need to hit the power button to wake it up if the lid open does not do it. Apart from that little glitch, it works extremely reliably.
