[Acer Extensa 5620] suspend/resume failure Ubuntu 9.10

[bdot]

Suspend/Resume never worked on this laptop, tried 8.10, 9.04, 9.10. Then, after the latest kernel upgrade, I gave it another shot and it worked! Great!
Well, almost...
Unfortunately, it appears as if a suspend/resume works within 15 minutes or so. But it failed when I left the laptop in Suspend overnight (although always on AC power).
Also, when rebooting, it hard-locked the laptop--required over a dozen power-on attempts to finally get the screen to light up and the computer to boot. This, however, always occurred even with the previous distros/kernels.

ProblemType: KernelOops
Annotation: This occured during a previous suspend and prevented it from resuming properly.

Upgraded kernel, but same results when suspending overnight (8 hours, this time):

Linux 2.6.31-8-generic #28-Ubuntu SMP Thu Aug 27 14:43:30 UTC 2009 i686 GNU/Linux

Again same problem with 2.6.31:

Linux 2.6.31-10-generic #34-Ubuntu SMP Wed Sep 16 00:23:19 UTC 2009 i686 GNU/Linux

Also, it showed up after approx. 4 hours of suspend (always on AC power). I still have to determine after how much time it locks up (suspend works fine for 0 to 45 minutes or so)

...Still same bug! It is strange how the problem only shows up after 4+ hours of suspend.

Linux 2.6.31-11-generic #38-Ubuntu SMP Fri Oct 2 11:55:55 UTC 2009 i686 GNU/Linux

BUMP BUMP BUMP

The problem is still here... it ain't goin' away!!

Linux 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:01:29 UTC 2009 i686 GNU/Linux

The only difference I noticed, now when it locks up (and still does, after approx. 4 hours in standby--even while connected to AC), it only takes a couple of power cycles to actually restart: it used to take about a dozen power-on attempts to actually restart the laptop (i.e. press power button, you hear the CD head moving but screen didn't light up and laptop didn't boot. then, after a couple of seconds, the cycle started over, again to no avail.)

Yeyy! Confirmed--at last! But any action?

Also, please note this affects Ubuntu 10.04 (latest kernel, everything updated yesterday) as well: laptop freezes if suspended overnight, otherwise resumes OK if resuscitated within approx 5 hours.

Suggest bug #350643 is merged with this -- looks like same problem.

[bdot (bdot)]

Upgraded to 10.04, then re-installed from scratch. Bug is still there.
