eth0 does not work when laptop battery is inserted

[tankdriver]

Steps to reproduce:
- shutdown Ubuntu
- start Ubuntu (thats important, do not use "reboot", you have to start manually)
- wired networking does not work (Did not get IP address)
- shutdown Ubuntu
- remove laptop battery and unplug powercable
- undo last step
- boot Ubuntu
- wired Network does work perfectly.

the steps above can be repeated infinitely.

My network is ok, (checked with other devices), I have already updated the BIOS.
This problem does appear at standby/hibernate/resume too.
Networking works under Win7.

Notebook Model: ASUS N90SC.

Hi tankdriver,

If you could also please 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.

ok, I installed and tested the mainline kernel located here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.13.4-lucid/

Its exactly the same behaviour as with the default kernel.

Furthermore, I noticed, that this bug can not be reproduced when "rebooting" ubuntu. You have to "shutdown/turnOFF" and start the laptop manually to get this bug. I will adjust the bug description.

tankdriver, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please 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 <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12-rc2

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
