I have the same problem on a new Thinkpad T40 laptop -- sometimes on unsuspend, I get to see the cursor for a second or so, and then it vanishes and the laptop goes back to sleep. It's not easy to reproduce -- the first time I managed to reproduce it while acpi_listen was running was today after a week of occasional trying -- but it does occur quite regularly. Relevant features:

 * Suspend was with a power cable plugged in and batteries fully charged; unsuspend was on battery power 45 mins later.
 * The wireless network changed between the suspend and unsuspend locations: on the second (successful) resume attempt, I got a dialog saying that the authentication credentials had been forgotten for the new wireless network (which I've used many times before)
 * This laptop has two batteries, which I've noticed has confused Ubuntu before (I get "critically low battery" warnings when battery #1 is near empty, even though battery #2 is full)

I think this may be related to bug #31935, but was urged to submit a new report rather than reopen that one... this one seems to be such a new bug on the same issue. I'll attach an acpi_listen log from this double-unsuspend in a moment.

Now repeated twice in a row, both times with the power plugged in when suspending and unplugged when resuming. The network details of my home network were forgotten the second time, but contrary to the report above I had suspended and resumed in the same location.

Any extra information wanted?

I tried your steps to reproduce this bug and worked twice in a row!
Definitely there is some issue with power management.

100% reproducible on my Fujitsu-Siemens Esprimo Mobile V5545, when I suspend / resume using the lid.

i have this bug as well on a Dell XPS M1330 running current 9.10

i have been trying to reproduce this bug consistently for several months and failing. just today it happened again -- twice:

1. suspend laptop via lid close, disconnect power, resume on battery. laptop immediately resuspends. 2nd resume attempt is successful.
2. suspend laptop via lid close, reconnect power, resume on AC. laptop immediately resuspends. 2nd resume attempt is successful.

maybe it has less to do with the state of the power (AC vs battery) as it does with a power state *change* while suspended?

I'm seeing this issue (or something *very* similar) on my MacBook 2,1 64bit karmic.

Log attached:
1) Close lid while on AC
2) open lid while on battery
3) Spontaneous suspend while entering password
4) Resume by pressing power button

There are a couple of warning call traces in the log, but I suspect they should be processed in a separate issue.

Can someone run the following commands, and post the output of the second
command after a double-suspend issue?
$ killall gnome-power-manager
$ gnome-power-manager --verbose

Here's my output of gnome-power-manager --verbose when reproducing this bug (sleep, plug off power, resume, laptop goes automatically to sleep in a few seconds, resume again).

Looks like gnome-power-manager is at fault there, suspending twice. I'm
declaring pm-utils innocent.

I'm confirming the gnome-power-manager bug. It's reproducible by setting both
battery and ac-power lid-action to suspend. I believe that upon resume, before
the lid status is internally updated by g-p-m, the battery status is updated,
and the policy action activated.

I can also note that my older laptop - HP Compaq NX6325 - is not
affected by this issue. It has the same version of Ubuntu installed
(9.10 64bit).
If you want I can post the output of g-p-m --verbose from it for comparison.

Please do. I think it might be useful.

Here's a debdiff that fixes the issue. Patch included inside has been forwarded
upstream already.

Logs from an unaffected laptop - HP Compaq NX6325.
Tried both suspending on AC + resuming on battery and vice versa.

This is an update to my previous comment:
my HP laptop is affected after all. See the attached logs.
It turns out that this issue happens only when you suspend the laptop by closing the lid (default gpm settings suspend the laptop on lid close). Suspending by using a menu option doesn't trigger this bug.

looks like the same bug as bug #480492, https://bugs.launchpad.net/ubuntu/+bug/480492

Another possibly related bug: Bug #425411
