[Bug 1533323] Re: Linux kernel holds lost ethernet connections


Patrick Nilsson, at your earliest convenience, could you please test the
latest upstream kernel available from the very top line at the top of
the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
(the release names are irrelevant for testing, and please do not test
the daily folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

  Linux kernel holds lost ethernet connections

Status in linux package in Ubuntu:

Bug description:
  If a connection to a router is lost while you have active ethernet
  connections to hosts (on the Internet), networking can't be resumed
  before all connections are closed. Many software packages repeatedly
  try to resume their lost connections, which must lead to a human
  intervention to quit all software before the connection to the router
  is re-established.

  Seems as it is the kernel that prevents connections to the router, by
  holding lost connections.

  Even if you in disable networking by selecting "Enable Networking"
  from the drop down menu, and re-enable it, you can't get through to
  the router before all user software has quit and closed all
  connections holding the lost host connections.

  This bug has existed for a long time(=years), but I have never learnt
  what the error could be.
