10ec:8139 [Lenovo N100] Ethernet overrun errors during TCP transfer when ACPI switched on

[Neil Wilson]

Still getting ethernet overrun errors in Ubuntu Precise on the RT 8139 ethernet driver.

Neil Wilson, thank you for reporting this and helping make Ubuntu better. 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.

Adding nolapic_timer to the boot line makes the overruns go away, but the side effects are problematic. The laptop fan stays on all the time and there are intermittent races in the GUI interface that slow it down to a crawl.

Marking Triaged High as mainline was tested and this being a problem with an essential hardware component (built-in networking).

@Neil,

Do you know if this issue happened in a previous version of Ubuntu, or is this a new issue you first started seeing in Precise?

[Neil Wilson (neil-aldur)]

It's been a problem for a very long time. This is a refresh bug for #401891

[Neil Wilson (neil-aldur)]

Bug 401891

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

[Neil Wilson (neil-aldur)]

I'm presuming that is an automated message. In which case it didn't pick up the upstream kernel bug this ticket is already linked to.
