Computer won't enter suspend mode.
These are the last lines of syslog (suspect ipv6 has something to do with this):

Hi velis,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 366182

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 . 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. Please let us know your results.

Thanks in advance.

Dear Jeremy. I no longer have the MB in question nor Ubuntu on the affected computer. Together with some other problems Ubuntu turned out as inappropriate for my usage scenarios.
Therefore I switched to another OS which had fewer issues.
I'm sorry, but I can't help with this issue any more.
