ethernet chokes with wake-on-lan deactivated

[Traumflug]

This is a curious one and all administrative attempts to narrow down the source of the problem failed. The symptoms:

- When booting off the Live CD, network is running just fine.

- After installation, on the first boot, too.

- After another reboot, ethernet doesn't work at all, DHCP doesn't pick up.

Further investigation:

- To satisfy the connection indicatior in the top Gnome menu bar, I can set up ethernet manually with the default-installed tool (network-manager-gnome?). Still, pings to computers in the same network report "Destination unreachable". ifconfig, in turn, reports what I'd expect for a working ethernet device, IPv4 and IPv6.

- Attempts to blacklist ipv6 failed, but that's another story.

Workaround

Just by chance I found this report in german which describes pretty much what I experienced:

At the bottom you see a screenshot from MS Windows. He explains how enabling Wake-On-Lan in MS Windows solves his networking problems in Ubuntu. Exactly as it did in my situation.

Btw., upgrading to the most current kernel, 2.6.28-11.42 doesn't make a difference.

Hi Traumflug,

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/lucid.

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 367233

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.
