I did a general upgrade a few days ago, rebooted, and now pm-hibernate usually doesn't work properly. It appears to save to swap correctly and resume correctly, but after 100% is read from disk the screen usually goes black, there's a pause of a few seconds, and it reboots.
Sometimes it does work correctly, so that it returns to the computer's state at the time of hibernation. It had been working reliably since I installed Arch a month or so ago, and the pm-suspend log looks the same as it did even when resume ends up failing.
It doesn't seem to matter what programs are running at the time of hibernation. (I tried hibernating immediately after booting, without logging onto any account, and same problem.) Any ideas what the problem might be?

Exactly the same here, on a Asus EEEPC 1005HA.
Did you solve it?
Offline
No. I looked around and it seems the issue arises now and then but it's not clear whether or how anybody solves it. Mine's an MSI Wind U100, by the way.

Same problem here on my eeePC 1001P. The most recent version where pm-hibernate works reliably is 2.6.38.5 Downgrading the kernel is a temporary workaround but obvious not a viable long term solution.
edit: The problems are exactly the same using uswsusp as the backend.

The same problem.
Linux serenity 2.6.38-ARCH #1 SMP PREEMPT Mon May 23 20:04:02 UTC 2011 i686 Intel(R) Atom(TM) CPU N450 @ 1.66GHz GenuineIntel GNU/Linux
eMachines 350-21G16i.
Become after last -Syu few days ago...
Any tips how to fix that?

Got the same problem.
I have upgraded kernel to 2.6.39-1 from [testing] and the hibernation is working again. At least for now.
Offline
Last update resolved this problem for me.
core/kernel26 2.6.38.8-1 (base)
Offline
Last update, to 2.6.39, seems to have fixed the problem or at least made it bearable--out of 8 hibernates 7 resumed properly. I think the one that didn't work had a problem because I was running Win XP in VirtualBox and Win XP has its own idea what to do when I close the lid (which is what triggered hibernation).

So... [SOLVED]?
Offline
Thawing from hibernate is better (less bad) for me with 2.6.39 but still not perfect -- 3 of 6 attempts failed, compared to < 2.6.38-5 which was 100% reliable.
Offline
I've still got a bit of a problem--usually it works (80-85% of the time) but sometimes not. No clear pattern when it does and when it doesn't. Before this all started it always worked. So maybe it's not really [SOLVED].

I am still experiencing the same issues with 2.6.39.2. It appears to be slightly more reliable when thawing while on ac power but it still fails about once every 4 or 5 attempts.
Offline
I had to downgrade to:
kernel26-2.6.38.5-1
Now it works 100% of the time.
Remember to use the "ignore" option when upgrading the system:
pacman -Syu --ignore kernel26

2.6.39.3 on asus 1005ha makes "at least" 1 out of 2 hibernation fails and reboot on resume.
-EDIT-
I'm trying to use linux 3.0-1 from testing and i'm still crossing my fingers because 5/5 resume attemps SUCCEDED by now!
-EDIT2 (OT)-
Tweaking via powertop-git makes power consumption low to 5.56..5.90W in idling, i don't think i've ever had it so low.

I'm having the same issues with a System76 Starling s4 netbook (see https://bbs.archlinux.org/viewtopic.php?pid=965112); downgrading to 2.6.38.5-1 solves the problem, but every subsequent non-[testing] version of kernel26 I've tried so far exhibits the issue for me.
Searching around on the 'net, there seems to be other folks having similar issue on other distros, mostly with netbook systems, but no answers. Anyone have a sense of what might have changed between 2.6.38.5 and 2.6.38.6 that might be a reasonable guess as to the cause of this problem? I'd really like to get hibernate working and I'm not afraid to recompile my kernel to do it, but I'd rather not go into the process blind...

I can second kokoko3k's experience that using the linux 3.0-1 package from [testing] rather than the stable kernel26 package seems to resolve the issue. As a bonus to folks like me, the rtl8192se driver is now included in the linux kernel tree, and thus doesn't need to be re-installed from AUR.

The upgrade to 3.0 seems to solve the problem absolutely. I had another problem with the VirtualBox modules causing hibernation to fail, but that seems irrelevant to this issue. (I solved that one by writing a script unloading the modules before hibernating and then reloading them on resume.)
So I'll mark the issue solved.
