Bug Description

On my hardware Maverick sometimes fails to resume from suspend. This happens with varying frequency: sometimes I can go for a few days (with 2-3 sleep/wake cycles per day) and other times it happens several times per day. I have to hit the power button to force a shutdown, then wait, then reboot.

It never gets to the point of activating the screen or an external monitor, and does not respond to CTRL-ALT-Delete.

The laptop used to suspend/resume reliably with Maverick. However, in one respect Maverick is an improvement: under both Karmic and Lucid, it would often take ~20 seconds to resume. With Maverick, when it works, it resumes essentially instantly.

I've saved a couple of extra files (kern.log and syslog), if you want them. After it failed to wake one time (Feb 13 11:54:01), I did have one reboot to fix an apparently-unrelated issue (graphical corruption when using KMS, I turned off KMS and rebooted).

Tim Holy, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

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/DebuggingKernelSuspend ? 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>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested.

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', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
