suspend to ram won't work anymore after upgrading to feisty

After further diggin' in launchpad, now I'm think that this might be a duplicate of #89983. But I'm not sure.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for this particular version of the kernel. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .
However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ .
If you do decide to test with the development release of Ubuntu please comment on this bug report and include at least the minimal information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help.

Brian, thanks for your comments.

Last time I checked (with Feisty LiveCD, actually), this kind of thing couldn't be tested with the LiveCD, because suspend and hibernation were disabled. Is this now enabled in Gutsy LiveCD, *without* installing it?

I'm willing to give Tribe 5 a spin... but only if someone can confirm that this features are enabled on the Live CD.

That is why I mentioned it, however only Suspend aka suspend to RAM will
be testable. As there is no physical drive partition used for swap the
Live CD, Hibernation aka suspend to disk will not be testable.

I can confirm that suspend to ram works again in Gutsy Tribe 5.

I have some (minor?) issues after resume:

 * Sometimes (but not always) g-p-m will pop the notification telling me that the computer failed to suspend, which is wrong.

 * Sometimes (but not always) I get a black screen, and I have to swhich back-and-forth from virtual screen 7 to a text console to get video again.

 * The sound is muted, always.

 * After resume, something with the wireless subsystem ends up totally messed up, and I can no longer connect to my wireless network.

... but I assume all of those are not kernel bugs, and have to do more with hal and/or the suspend/resume scripts or something.

It would be helpful if you were to submit all of these issues as
separate bug reports so we can work on getting them resolved in Gutsy.

The package for that bug should be gnome-power-manager.

The package for that bug should be xorg, please include
'/etc/X11/xorg.conf' and '/var/log/Xorg.0.log' after resuming.

The package for that bug would be linux-source-2.6.22, please include
the output requested at https://wiki.ubuntu.com/DebuggingSoundProblems .

This could be network-manager or your wireless driver.
