vawa, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012. /wiki.ubuntu. com/Releases
Please see this document for currently supported Ubuntu releases:
https:/
We were wondering if this is still an issue in a supported release? If so, could you please provide the information following https:/ /wiki.ubuntu. com/DebuggingKe rnelSuspendHibe rnateResume ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http:// cdimage. ubuntu. com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command in the development release from a Terminal (Applications- >Accessories- >Terminal) as it will automatically gather and attach updated debug information to this report.
apport-collect -p linux <BUGNUMBER>
Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Please let us know your results. Thanks in advance.
