after locking ubuntu for some time, ubuntu doesn't connect to network, though it tries to

[Antony]

I am used to locking my ubuntu. Recently I upgraded to Ubuntu 11.10 Beta 2 from Ubuntu 11.04. After upgradation, whenever I lock my ubuntu, It seems to loose network connection. After sometime when I unlock my ubuntu, it tries to connect to ethernet LAN. But it always fails. I am forced to reboot or some other command could help me.

Antony, thank you for reporting this and helping make Ubuntu better. 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 <replace-with-bug-number>

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.

Antony Raj.
