OS can't hiberate and suspend.

[zshaooo]

Hardware: Montevina(HP-prototype-laptop)
Software: Intrepid-beta-x86

Steps to reproduce:

Click "System-->shutdown...-->Suspend" of Gnome Desktop.Expect the system become S3 status(suspend),but a Login-Window appeared at once after clicking,with screen power on still.
Clicking "System-->shutdown...-->Hibernate" also reproduce the bug.

More debug informations are in attachment.

I just upgraded from Hardy to Intrepid. And I have the exact same issue. Also, my User Session doesn't list Hibernate anymore (I don't use Suspend). I thought I read this was an issue with pm-utils, but I checked and I am running the latest version according to Update-Manager.

FYI, Hibernate worked perfectly for me under Hardy (Dell Latitude).

The driver of some device can't handle the suspend/hibernate event as expected from our investigation.
After upgraded to Intrepid final, we can't reproduce it on HP-2230s.

But I can still reproduce this issue on SONY Vaio VGN-Z540. There's a patch fixing this bug for the SONY laptop which already in kernel 2.6.28-rc3:

    sony-laptop: ignore missing _DIS method on pic device

    At least the Vaio VGN-Z540N doesn't have this method, so let's not fail
    to suspend just because it doesn't exist.

Bug exists also on a Gigabyte GA-8S648FX motherboard with Interpid.
In some cases Ubuntu may refuse to hibernate, others it logs me out and others it just shuts down.

Bug exists also on a VIA EPIA EN12000E with Interpid.

Intrepid Ibex reached end-of-life on 30 April 2010 so I am closing the report. The bug has been fixed in newer releases of Ubuntu.
